Merge branch 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs

Pull ext3 removal, quota & udf fixes from Jan Kara:
 "The biggest change in the pull is the removal of ext3 filesystem
  driver (~28k lines removed).  Ext4 driver is a full featured
  replacement these days and both RH and SUSE use it for several years
  without issues.  Also there are some workarounds in VM & block layer
  mainly for ext3 which we could eventually get rid of.

  Other larger change is addition of proper error handling for
  dquot_initialize().  The rest is small fixes and cleanups"

[ I wasn't convinced about the ext3 removal and worried about things
  falling through the cracks for legacy users, but ext4 maintainers
  piped up and were all unanimously in favor of removal, and maintaining
  all legacy ext3 support inside ext4.   - Linus ]
