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

Pull pile 2 of vfs updates from Al Viro:
 "Stuff in this one - assorted fixes, lglock tidy-up, death to
  lock_super().

  There'll be a VFS pile tomorrow (with patches from Jeff Layton,
  sanitizing getname() and related parts of audit and preparing for
  ESTALE fixes), but I'd rather push the stuff in this one ASAP - some
  of the bugs closed here are quite unpleasant."

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
  vfs: bogus warnings in fs/namei.c
  consitify do_mount() arguments
  lglock: add DEFINE_STATIC_LGLOCK()
  lglock: make the per_cpu locks static
  lglock: remove unused DEFINE_LGLOCK_LOCKDEP()
  MAX_LFS_FILESIZE definition for 64bit needs LL...
  tmpfs,ceph,gfs2,isofs,reiserfs,xfs: fix fh_len checking
  vfs: drop lock/unlock super
  ufs: drop lock/unlock super
  sysv: drop lock/unlock super
  hpfs: drop lock/unlock super
  fat: drop lock/unlock super
  ext3: drop lock/unlock super
  exofs: drop lock/unlock super
