From d36ccb9cec22a09a12d9ef8234d634f840d7ae4b Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Wed, 15 May 2013 10:46:33 -0700 Subject: [PATCH] SUNRPC: Fix a bug in gss_create_upcall If wait_event_interruptible_timeout() is successful, it returns the number of seconds remaining until the timeout. In that case, we should be retrying the upcall.
