From 0bae89ec8b1519dae67036637942f5b5bbaa9424 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sun, 8 Oct 2006 14:33:24 -0400 Subject: [PATCH] NFS: Fix typo in nfs_get_client() Commit ca4aa09635516258f158a7bc1594a794e4c34864 fixed waiting for the structure to get initialised, but it is also possible to break out of the loop while still in TASK_INTERRUPTIBLE. Replace the whole thing by wait_event_interruptible, which is much more readable, and doesn't suffer from these problems.
