Merge branch 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs
Pull quota interface unification and misc cleanups from Jan Kara:
"The first part of the series unifying XFS and VFS quota interfaces.
This part unifies turning quotas on and off so quota-tools and
xfs_quota can be used to manage any filesystem. This is useful so
that userspace doesn't have to distinguish which filesystem it is
working with. As a result we can then easily reuse tests for project
quotas in XFS for ext4.
This also contains minor cleanups and fixes for udf, isofs, and ext3"
* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs: (23 commits)
udf: remove bool assignment to 0/1
udf: use bool for done
quota: Store maximum space limit in bytes
quota: Remove quota_on_meta callback
ocfs2: Use generic helpers for quotaon and quotaoff
ext4: Use generic helpers for quotaon and quotaoff
quota: Add ->quota_{enable,disable} callbacks for VFS quotas
quota: Wire up ->quota_{enable,disable} callbacks into Q_QUOTA{ON,OFF}
quota: Split ->set_xstate callback into two
xfs: Remove some pointless quota checks
xfs: Remove some useless flags tests
xfs: Remove useless test
quota: Verify flags passed to Q_SETINFO
quota: Cleanup flags definitions
ocfs2: Move OLQF_CLEAN flag out of generic quota flags
quota: Don't store flags for v2 quota format
jbd: drop jbd_ENOSYS debug
udf: destroy sbi mutex in put_super
udf: Check length of extended attributes and allocation descriptors
udf: Remove repeated loads blocksize

This is a file system used on some CD-ROMs and DVDs. Since the

file system is supported by multiple operating systems and is more

compatible with standard unix file systems, it is also suitable for

removable USB disks. Say Y if you intend to mount DVD discs or CDRW's

written in packet mode, or if you want to use UDF for removable USB

disks. Please read <file:Documentation/filesystems/udf.txt>.

To compile this file system support as a module, choose M here: the

module will be called udf.
