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")"
