Path deletion\nflushes the cache and then frees the path with kfree_rcu(), but a\nlookup that already holds the path can insert a new cache entry\nafter the flush. The cache then points at freed memory.\n\nSet MESH_PATH_DELETED before flushing, and skip inserting a cache\nentry if the path or MPP path is already deleted. Check this under\nthe cache walk lock so it is ordered with the flush. Use WRITE_ONCE()\nfor the deletion flag updates because the cache check reads flags\nwithout taking state_lock."
