Pull quota, ext2, isofs and udf fixes from Jan Kara: - two small quota error handling fixes - two isofs fixes for architectures with signed char - several udf block number overflow and signedness fixes - ext2 rework of mount option handling to avoid GFP_KERNEL allocation with spinlock held - ... it also contains a patch to implement auditing of responses to fanotify permission events. That should have been in the fanotify pull request but I mistakenly merged that patch into a wrong branch and noticed only now at which point I don't think it's worth rebasing and redoing. * 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs: quota: be aware of error from dquot_initialize quota: fix potential infinite loop isofs: use unsigned char types consistently isofs: fix timestamps beyond 2027 udf: Fix some sign-conversion warnings udf: Fix signed/unsigned format specifiers udf: Fix 64-bit sign extension issues affecting blocks > 0x7FFFFFFF udf: Remove some outdate references from documentation udf: Avoid overflow when session starts at large offset ext2: Fix possible sleep in atomic during mount option parsing ext2: Parse mount options into a dedicated structure audit: Record fanotify access control decisions
