* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-udf-2.6:
udf: Don't write integrity descriptor too often
udf: Try anchor in block 256 first
udf: Some type fixes and cleanups
udf: use hardware sector size
udf: fix novrs mount option
udf: Fix oops when invalid character in filename occurs
udf: return f_fsid for statfs(2)
udf: Add checks to not underflow sector_t
udf: fix default mode and dmode options handling
udf: fix sparse warnings:
udf: unsigned last[i] cannot be less than 0
udf: implement mode and dmode mounting options
udf: reduce stack usage of udf_get_filename
udf: reduce stack usage of udf_load_pvoldesc
Fix the udf code not to pass structs on stack where possible.
Remove struct typedefs from fs/udf/ecma_167.h et al.
gid= Set the default group.
umask= Set the default umask.
+ mode= Set the default file permissions.
+ dmode= Set the default directory permissions.
uid= Set the default user.
bs= Set the block size.
unhide Show otherwise hidden files.
