Pull vfs fixes from Al Viro: - backport-friendly part of lock_parent() race fix - a fix for an assumption in the heurisic used by path_connected() that is not true on NFS - livelock fixes for d_alloc_parallel() * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: fs: Teach path_connected to handle nfs filesystems with multiple roots. fs: dcache: Use READ_ONCE when accessing i_dir_seq fs: dcache: Avoid livelock between d_alloc_parallel and __d_add lock_parent() needs to recheck if dentry got __dentry_kill'ed under it
