Merge branch 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull misc fixes from Al Viro:
"vhost race fix and a percpu_ref_init-caused cgroup double-free fix.
The latter had manifested as buggered struct mount refcounting - those
are also using percpu data structures, but anything that does percpu
allocations could be hit"
* 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
Fix double fget() in vhost_net_set_backend()
percpu_ref_init(): clean ->percpu_count_ref on failure
