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
