Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/bcopeland/omfs

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/bcopeland/omfs:
  omfs: make readdir stop when filldir says so
  omfs: merge unlink() and rmdir(), close leak in rename()
  omfs: stop playing silly buggers with omfs_unlink() in ->rename()
  omfs: rename() needs to mark old_inode dirty after ctime update
