* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs-2.6: quota: Improve checking of quota file header jbd: jbd-debug and jbd2-debug should be writable ext4: fix sleep inside spinlock issue with quota and dealloc (#14739) ext4: Fix potential quota deadlock quota: Fix 64-bit limits setting on 32-bit archs ext3: Replace lock/unlock_super() with an explicit lock for resizing ext3: Replace lock/unlock_super() with an explicit lock for the orphan list ext3: ext3_mark_recovery_complete() doesn't need to use lock_super ext3: Remove outdated comment about lock_super() quota: Move duplicated code to separate functions ext4: Convert to generic reserved quota's space management. quota: decouple fs reserved space from quota reservation Add unlocked version of inode_add_bytes() function ext3: quota macros cleanup [V2]
