Merge tag 'bcachefs-2024-03-13' of https://evilpiepirate.org/git/bcachefs
Pull bcachefs updates from Kent Overstreet:
- Subvolume children btree; this is needed for providing a userspace
interface for walking subvolumes, which will come later
- Lots of improvements to directory structure checking
- Improved journal pipelining, significantly improving performance on
high iodepth write workloads
- Discard path improvements: the discard path is more efficient, and no
longer flushes the journal unnecessarily
- Buffered write path can now avoid taking the inode lock
- new mm helper: memalloc_flags_{save|restore}
- mempool now does kvmalloc mempools
