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

Pull ext3, reiserfs, udf & isofs fixes from Jan Kara:
 "The contains a bunch of ext3 cleanups and minor improvements, major
  reiserfs locking changes which should hopefully fix deadlocks
  introduced by BKL removal, and udf/isofs changes to refuse mounting fs
  rw instead of mounting it ro automatically which makes eject button
  work as expected for all media (see the changelog for why userspace
  should be ok with this change)"

* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
  jbd: use a single printk for jbd_debug()
  reiserfs: locking, release lock around quota operations
  reiserfs: locking, handle nested locks properly
  reiserfs: locking, push write lock out of xattr code
  jbd: relocate assert after state lock in journal_commit_transaction()
  udf: Refuse RW mount of the filesystem instead of making it RO
  udf: Standardize return values in mount sequence
  isofs: Refuse RW mount of the filesystem instead of making it RO
  ext3: allow specifying external journal by pathname mount option
  jbd: remove unneeded semicolon
