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

Pull vfs stable fodder fixes from Al Viro:

 - acct_on() fix for deadlock caught by overlayfs folks

 - autofs RCU use-after-free SNAFU (->d_manage() can be called
   locklessly, so we need to RCU-delay freeing the objects it looks at)

 - (hopefully) the end of "do we need freeing this dentry RCU-delayed"
   whack-a-mole.

* 'stable-fodder' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
  autofs: fix use-after-free in lockless ->d_manage()
  dcache: sort the freeing-without-RCU-delay mess for good.
  acct_on(): don't mess with freeze protection
