From 47051a2152f8b2355ee70249a0faaf7b682e8ce5 Mon Sep 17 00:00:00 2001 From: David Howells Date: Fri, 27 Apr 2007 15:26:30 -0700 Subject: [PATCH] [AFS]: Fix VLocation record update wakeup Fix the wakeup transitions after a VLocation record update completes one way or another. This builds on Dave Miller's partial fix. Also move wakeups outside the spinlocked sections. Signed-off-by: David Howells Signed-off-by: David S.
