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 <daniel.wagner@bmw-carit.de> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
