Commit 804a007f authored by Linus Torvalds's avatar Linus Torvalds

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6:
  cifs: propagate errors from cifs_get_root() to mount(2)
  cifs: tidy cifs_do_mount() up a bit
  cifs: more breakage on mount failures
  cifs: close sget() races
  cifs: pull freeing mountdata/dropping nls/freeing cifs_sb into cifs_umount()
  cifs: move cifs_umount() call into ->kill_sb()
  cifs: pull cifs_mount() call up
  sanitize cifs_umount() prototype
  cifs: initialize ->tlink_tree in cifs_setup_cifs_sb()
  cifs: allocate mountdata earlier
  cifs: leak on mount if we share superblock
  cifs: don't pass superblock to cifs_mount()
  cifs: don't leak nls on mount failure
  cifs: double free on mount failure
  take bdi setup/destruction into cifs_mount/cifs_umount
