Merge branch 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs
Pull quota and udf updates from Jan Kara: "The pull contains quota changes which complete unification of XFS and VFS quota interfaces (so tools can use either interface to manipulate any filesystem). There's also a patch to support project quotas in VFS quota subsystem from Li Xi. Finally there's a bunch of UDF fixes and cleanups and tiny cleanup in reiserfs & ext3" * 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs: (21 commits) udf: Update ctime and mtime when directory is modified udf: return correct errno for udf_update_inode() ext3: Remove useless condition in if statement. vfs: Add general support to enforce project quota limits reiserfs: fix __RASSERT format string udf: use int for allocated blocks instead of sector_t udf: remove redundant buffer_head.h includes udf: remove else after return in __load_block_bitmap() udf: remove unused variable in udf_table_free_blocks() quota: Fix maximum quota limit settings quota: reorder flags in quota state quota: paranoia: check quota tree root quota: optimize i_dquot access quota: Hook up Q_XSETQLIM for id 0 to ->set_info xfs: Add support for Q_SETINFO quota: Make ->set_info use structure with neccesary info to VFS and XFS quota: Remove ->get_xstate and ->get_xstatev callbacks gfs2: Convert to using ->get_state callback xfs: Convert to using ->get_state callback quota: Wire up Q_GETXSTATE and Q_GETXSTATV calls to work with ->get_state ...
