    Pull misc vfs updates from Al Viro:
     "Making sure that something like a referral point won't end up as pwd
      or root.
      The main part is the last commit (fixing mntns_install()); that one
      fixes a hard-to-hit race. The fchdir() commit is making fchdir(2) a
      bit more robust - it should be impossible to get opened files (even
      O_PATH ones) for referral points in the first place, so the existing
      checks are OK, but checking the same thing as in chdir(2) is just as
      The path_init() commit removes a redundant check that shouldn't have
      been there in the first place"
    * 'work.sane_pwd' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
      make sure that mntns_install() doesn't end up with referral for root
      path_init(): don't bother with checking MAY_EXEC for LOOKUP_ROOT
      make sure that fchdir() won't accept referral points, etc.
