Merge branch 'generic' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs
Pull quota, reiserfs, udf and ext2 updates from Jan Kara: "The branch contains changes to quota code so that it does not modify persistent flags in inode->i_flags (it was the only place in kernel doing that) and handle it inside filesystem's quotaon/off handlers instead. The branch also contains two UDF cleanups, a couple of reiserfs fixes and one fix for ext2 quota locking" * 'generic' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs: ext4: Improve comments in ext4_quota_{on|off}() udf: use kmap_atomic for memcpy copying udf: use octal for permissions quota: Remove dquot_quotactl_ops reiserfs: Remove i_attrs_to_sd_attrs() reiserfs: Remove useless setting of i_flags jfs: Remove jfs_get_inode_flags() ext2: Remove ext2_get_inode_flags() ext4: Remove ext4_get_inode_flags() quota: Stop setting IMMUTABLE and NOATIME flags on quota files jfs: Set flags on quota files directly ext2: Set flags on quota files directly reiserfs: Set flags on quota files directly ext4: Set flags on quota files directly reiserfs: Protect dquot_writeback_dquots() by s_umount semaphore reiserfs: Make cancel_old_flush() reliable ext2: Call dquot_writeback_dquots() with s_umount held reiserfs: avoid a -Wmaybe-uninitialized warning
