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

Pull single_open() leak fixes from Al Viro:
 "A bunch of fixes for a moderately common class of bugs: file with
  single_open() done by its ->open() and seq_release as its ->release().

  That leaks; fortunately, it's not _too_ common (either people manage
  to RTFM that says "When using single_open(), the programmer should use
  single_release() instead of seq_release() in the file_operations
  structure to avoid a memory leak", or they just copy a correct
  instance), but grepping through the tree has caught quite a pile.

  All of that is, AFAICS, -stable fodder, for as far as the patches
  apply.  I tried to carve it up into reasonably-sized pieces (more or
  less "comes from the same tree")"
