Hello Linus,
could you please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs.git for_linus
to get changes to locking of some quota operations from dedicated quota mutex
to s_umount semaphore, a fsnotify fix and a simple ext2 fix.
Top of the tree is 5716863e0f82. The full shortlog is:
Darrick J. Wong (1):
ext2: reject inodes with negative size
Jan Kara (8):
fs: Provide function to get superblock with exclusive s_umount
quota: Hold s_umount in exclusive mode when enabling / disabling quotas
quota: Use s_umount protection for quota operations
ocfs2: Protect periodic quota syncing with s_umount semaphore
quota: Remove dqonoff_mutex from dquot_scan_active()
ocfs2: Use s_umount for quota recovery protection
quota: Remove dqonoff_mutex
fsnotify: Fix possible use-after-free in inode iteration on umount
The diffstat is
fs/ext2/inode.c | 4 ++
fs/notify/inode_mark.c | 45 ++++------------
fs/ocfs2/quota_global.c | 10 +++-
fs/ocfs2/quota_local.c | 11 ++--

Just after sending this pull request I've received a report from 0-day
testing that a warning in dquot_disable() hits on remount. It is just a
cosmetic thing but still I'd prefer to have this fixed and not have to deal
with reports of this warning. So I have pushed out one additional commit
to for_linus branch:
2700e6067c72 "quota: Fix bogus warning in dquot_disable()"
Sorry for the noise. I'm now going to dig into why my personal testing
didn't actually spot this earlier...
