From 4d4471cb5c1ec426c0f24818b270dc7b3ad7e655 Mon Sep 17 00:00:00 2001 From: Kiyoshi Ueda Date: Thu, 10 Dec 2009 23:52:26 +0000 Subject: [PATCH] dm: swap target postsuspend call and setting suspended flag This patch moves DMF_SUSPENDED flag set before postsuspend. No one should care about the ordering, because the flag set and the postsuspend are protected by a single lock, md->suspend_lock, and all strict flag-checkers take the lock.
