From 2a446a5d99fe838b8aba2592a4bc88d93d8cebf8 Mon Sep 17 00:00:00 2001 From: Daniel Wagner Date: Thu, 22 Sep 2016 13:54:29 +0200 Subject: NFS: cache_lib: use complete() instead of complete_all() There is only one waiter for the completion, therefore there is no need to use complete_all(). Let's make that clear by using complete() instead of complete_all(). The generic caching code from sunrpc is calling revisit() only once. The usage pattern of the completion is: waiter context waker context do_cache_lookup_wait() nfs_cache_defer_req_alloc() init_completion() do_cache_lookup() nfs_cache_wait_for_upcall() wait_for_completion_timeout() nfs_dns_cache_revisit() complete() nfs_cache_defer_req_put() Signed-off-by: Daniel Wagner Signed-off-by: Anna Schumaker --- fs/nfs/cache_lib.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'fs/nfs') diff --git a/fs/nfs/cache_lib.c b/fs/nfs/cache_lib.c index 5f7b053720ee..6de15709d024 100644 --- a/fs/nfs/cache_lib.c +++ b/fs/nfs/cache_lib.c @@ -76,7 +76,7 @@ static void nfs_dns_cache_revisit(struct cache_deferred_req *d, int toomany) dreq = container_of(d, struct nfs_cache_defer_req, deferred_req); - complete_all(&dreq->completion); + complete(&dreq->completion); nfs_cache_defer_req_put(dreq); } -- cgit v1.2.3
