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
