* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
  udf: Fix loading of special inodes
  ocfs2: Back out change to use OCFS2_MAXQUOTAS in ocfs2_setattr()
  udf: remove redundant sys_tz declaration
  ocfs2: Don't use MAXQUOTAS value
  reiserfs: Don't use MAXQUOTAS value
  ext3: Don't use MAXQUOTAS value
  udf: Fix race between write(2) and close(2)
