From 63859d4fe4c97b737e7adbfe60acb1c2b2e668cb Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Tue, 15 Sep 2009 19:14:42 +0200 Subject: [PATCH] sched: Fix sync wakeups again The sync argument rename to introduce WF_* broke stuff by missing a local alias for an argument in __wake_up_common, fix it by using the more descriptive wake_flags name. This restores WF_SYNC propagation, which fixes wake_affine() behaviour, which fixes pipe-test.
