This is due to kernel include/linux/limits.h being included instead of
libc's limits.h.
This is because directory include/ is added through option -isystem so
it goes prior to glibc's include directory.
Replace -isystem by -idirafter.
But this implies that now tools/include/linux/linkage.h is included
instead of include/linux/linkage.h, so define a stub for
SYM_FUNC_START() and SYM_FUNC_END().

selftests: vDSO: simplify getrandom thread local storage and structs
Rather than using pthread_get/set_specific, just use gcc's __thread
annotation, which is noticeably faster and makes the code more obvious.
Also, just have one simplified struct called vgrnd, instead of trying to
split things up semantically. Those divisions were useful when this code
was split across several commit *messages*, but doesn't make as much
sense within a single file. This should make the code more clear and

btrfs: fix uninitialized return value from btrfs_reclaim_sweep()
The return variable 'ret' at btrfs_reclaim_sweep() is never assigned if
none of the space infos is reclaimable (for example if periodic reclaim
is disabled, which is the default), so we return an undefined value.
This can be fixed my making btrfs_reclaim_sweep() not return any value
as well as do_reclaim_sweep() because:
1) do_reclaim_sweep() always returns 0, so we can make it return void;
2) The only caller of btrfs_reclaim_sweep() (btrfs_reclaim_bgs()) doesn't
care about its return value, and in its context there's nothing to do
about any errors anyway.
Therefore remove the return value from btrfs_reclaim_sweep() and

[CAUSE]
Although I cannot reproduce the error, the report itself is good enough
to pin down the cause.
The call trace is the regular endio workqueue context, but the
free-by-task trace is showing that during btrfs_submit_chunk() we
already hit a critical error, and is calling btrfs_bio_end_io() to error
out. And the original endio function called bio_put() to free the whole
bio.
This means a double freeing thus causing use-after-free, e.g.:
1. Enter btrfs_submit_bio() with a read bio
The read bio length is 128K, crossing two 64K stripes.
2. The first run of btrfs_submit_chunk()
2.1 Call btrfs_map_block(), which returns 64K
2.2 Call btrfs_split_bio()
Now there are two bios, one referring to the first 64K, the other
referring to the second 64K.
2.3 The first half is submitted.
3. The second run of btrfs_submit_chunk()
3.1 Call btrfs_map_block(), which by somehow failed
Now we call btrfs_bio_end_io() to handle the error
3.2 btrfs_bio_end_io() calls the original endio function
Which is end_bbio_data_read(), and it calls bio_put() for the
original bio.
Now the original bio is freed.
4. The submitted first 64K bio finished
Now we call into btrfs_check_read_bio() and tries to advance the bio
iter.
But since the original bio (thus its iter) is already freed, we
trigger the above use-after free.
And even if the memory is not poisoned/corrupted, we will later call
the original endio function, causing a double freeing.
[FIX]
Instead of calling btrfs_bio_end_io(), call btrfs_orig_bbio_end_io(),
which has the extra check on split bios and do the proper refcounting
for cloned bios.
Furthermore there is already one extra btrfs_cleanup_bio() call, but
that is duplicated to btrfs_orig_bbio_end_io() call, so remove that
label completely.

fs/nfsd: fix update of inode attrs in CB_GETATTR
Currently, we copy the mtime and ctime to the in-core inode and then
mark the inode dirty. This is fine for certain types of filesystems, but
not all. Some require a real setattr to properly change these values
(e.g. ceph or reexported NFS).
Fix this code to call notify_change() instead, which is the proper way
to effect a setattr. There is one problem though:
In this case, the client is holding a write delegation and has sent us
attributes to update our cache. We don't want to break the delegation
for this since that would defeat the purpose. Add a new ATTR_DELEG flag
that makes notify_change bypass the try_break_deleg call.

If ParaVirt steal time feature is enabled, there is a percpu gpa address

However if VM is crashed and VMM reboots VM forcely, the vCPU reboot

Here it is invalidated from the vCPU KVM_REG_LOONGARCH_VCPU_RESET ioctl

We have transient failures with btrfs/301, specifically in the part

done
Sometimes this will result in a transient quota error, and it's because
sometimes we start writeback on the file which results in a delayed
iput, and thus the rm doesn't actually clean the file up. When we're
flushing the quota space we need to run the delayed iputs to make sure
all the unlinks that we think have completed have actually completed.
This removes the small window where we could fail to find enough space

cifs: Fix FALLOC_FL_PUNCH_HOLE support
The cifs filesystem doesn't quite emulate FALLOC_FL_PUNCH_HOLE correctly
(note that due to lack of protocol support, it can't actually implement it
directly). Whilst it will (partially) invalidate dirty folios in the
pagecache, it doesn't write them back first, and so the EOF marker on the
server may be lower than inode->i_size.
This presents a problem, however, as if the punched hole invalidates the
tail of the locally cached dirty data, writeback won't know it needs to
move the EOF over to account for the hole punch (which isn't supposed to
move the EOF). We could just write zeroes over the punched out region of
the pagecache and write that back - but this is supposed to be a
deallocatory operation.
Fix this by manually moving the EOF over on the server after the operation
if the hole punched would corrupt it.
Note that the FSCTL_SET_ZERO_DATA RPC and the setting of the EOF should
probably be compounded to stop a third party interfering (or, at least,
massively reduce the chance).
This was reproducible occasionally by using fsx with the following script:
truncate 0x0 0x375e2 0x0
punch_hole 0x2f6d3 0x6ab5 0x375e2
truncate 0x0 0x3a71f 0x375e2
mapread 0xee05 0xcf12 0x3a71f
write 0x2078e 0x5604 0x3a71f
write 0x3ebdf 0x1421 0x3a71f *

read 0x15f2 0x7d32 0x40000
read 0x32f37 0x7a3b 0x40000 *
The second "write" should extend the EOF to 0x40000, and the "punch_hole"
should operate inside of that - but that depends on whether the VM gets in
and writes back the data first. If it doesn't, the file ends up 0x3a71f in
size, not 0x40000.

pinctrl: rockchip: correct RK3328 iomux width flag for GPIO2-B pins
The base iomux offsets for each GPIO pin line are accumulatively
calculated based off iomux width flag in rockchip_pinctrl_get_soc_data.
If the iomux width flag is one of IOMUX_WIDTH_4BIT, IOMUX_WIDTH_3BIT or
IOMUX_WIDTH_2BIT, the base offset for next pin line would increase by 8
bytes, otherwise it would increase by 4 bytes.
Despite most of GPIO2-B iomux have 2-bit data width, which can be fit
into 4 bytes space with write mask, it actually take 8 bytes width for
whole GPIO2-B line.
Commit
e8448a6c817c ("pinctrl: rockchip: fix pinmux bits for RK3328
GPIO2-B pins") wrongly set iomux width flag to 0, causing all base
iomux offset for line after GPIO2-B to be calculated wrong. Fix the
iomux width flag to IOMUX_WIDTH_2BIT so the offset after GPIO2-B is
correctly increased by 8, matching the actual width of GPIO2-B iomux.

netfs: Fix interaction of streaming writes with zero-point tracker
When a folio that is marked for streaming write (dirty, but not uptodate,
with partial content specified in the private data) is written back, the
folio is effectively switched to the blank state upon completion of the
write. This means that if we want to read it in future, we need to reread
the whole folio.
However, if the folio is above the zero_point position, when it is read
back, it will just be cleared and the read skipped, leading to apparent
local corruption.
Fix this by increasing the zero_point to the end of the dirty data in the
folio when clearing the folio state after writeback. This is analogous to
the folio having ->release_folio() called upon it.
This was causing the config.log generated by configuring a cpython tree on
a cifs share to get corrupted because the scripts involved were appending
text to the file in small pieces.

netfs: Fix trimming of streaming-write folios in netfs_inval_folio()
When netfslib writes to a folio that it doesn't have data for, but that
data exists on the server, it will make a 'streaming write' whereby it
stores data in a folio that is marked dirty, but not uptodate. When it
does this, it attaches a record to folio->private to track the dirty
region.
When truncate() or fallocate() wants to invalidate part of such a folio, it
will call into ->invalidate_folio(), specifying the part of the folio that
is to be invalidated. netfs_invalidate_folio(), on behalf of the
filesystem, must then determine how to trim the streaming write record. In
a couple of cases, however, it does this incorrectly (the reduce-length and
move-start cases are switched over and don't, in any case, calculate the
value correctly).
Fix this by making the logic tree more obvious and fixing the cases.

afs: Fix post-setattr file edit to do truncation correctly
At the end of an kAFS RPC operation, there is an "edit" phase (originally
intended for post-directory modification ops to edit the local image) that
the setattr VFS op uses to fix up the pagecache if the RPC that requested
truncation of a file was successful.
afs_setattr_edit_file() calls truncate_setsize() which sets i_size, expands
the pagecache if needed and truncates the pagecache. The first two of
those, however, are redundant as they've already been done by
afs_setattr_success() under the io_lock and the first is also done under
the callback lock (cb_lock).
Fix afs_setattr_edit_file() to call truncate_pagecache() instead (which is
called by truncate_setsize(), thereby skipping the redundant parts.

nfsd: prevent panic for nfsv4.0 closed files in nfs4_show_open
Prior to commit
3f29cc82a84c ("nfsd: split sc_status out of
sc_type") states_show() relied on sc_type field to be of valid
type before calling into a subfunction to show content of a
particular stateid. From that commit, we split the validity of
the stateid into sc_status and no longer changed sc_type to 0
while unhashing the stateid. This resulted in kernel oopsing
for nfsv4.0 opens that stay around and in nfs4_show_open()
would derefence sc_file which was NULL.
Instead, for closed open stateids forgo displaying information
that relies of having a valid sc_file.
To reproduce: mount the server with 4.0, read and close
a file and then on the server cat /proc/fs/nfsd/clients/2/states

pinctrl: mediatek: common-v2: Fix broken bias-disable for PULL_PU_PD_RSEL_TYPE
Despite its name, commit
fed74d75277d ("pinctrl: mediatek: common-v2:
Fix bias-disable for PULL_PU_PD_RSEL_TYPE") actually broke bias-disable
for PULL_PU_PD_RSEL_TYPE.
mtk_pinconf_bias_set_combo() tries every bias method supported by the
pin until one succeeds. For PULL_PU_PD_RSEL_TYPE pins, before the
breaking commit, mtk_pinconf_bias_set_rsel() would be called first to
try and set the RSEL value (as well as PU and PD), and if that failed,
the only other valid option was that bias-disable was specified, which
would then be handled by calling mtk_pinconf_bias_set_pu_pd() and
disabling both PU and PD.
The breaking commit misunderstood this logic and added an early "return
0" in mtk_pinconf_bias_set_rsel(). The result was that in the
bias-disable case, the bias was left unchanged, since by returning
success, mtk_pinconf_bias_set_combo() no longer tried calling
mtk_pinconf_bias_set_pu_pd() to disable the bias.
Since the logic for configuring bias-disable on PULL_PU_PD_RSEL_TYPE
pins required mtk_pinconf_bias_set_rsel() to fail first, in that case,
an error was printed to the log, eg:
mt8195-pinctrl
10005000.pinctrl: Not support rsel value 0 Ohm for pin = 29 (GPIO29)
This is what the breaking commit actually got rid of, and likely part of
the reason why that commit was thought to be fixing functionality, while
in reality it was breaking it.
Instead of simply reverting that commit, restore the functionality but
in a way that avoids the error from being printed and makes the code
less confusing:
* Return 0 explicitly if a bias method was successful
* Introduce an extra function mtk_pinconf_bias_set_pu_pd_rsel() that
calls both mtk_pinconf_bias_set_rsel() (only if needed) and
mtk_pinconf_bias_set_pu_pd()
* And analogously for the corresponding getters

NFS: Avoid unnecessary rescanning of the per-server delegation list
If the call to nfs_delegation_grab_inode() fails, we will not have
dropped any locks that require us to rescan the list.

nfs: fix bitmap decoder to handle a 3rd word
It only decodes the first two words at this point. Have it decode the
third word as well. Without this, the client doesn't send delegated
timestamps in the CB_GETATTR response.
With this change we also need to expand the on-stack bitmap in
decode_recallany_args to 3 elements, in case the server sends a larger
bitmap than expected.
