From ed3b3d314cd2f16fac42676839854a68cab2e22b Mon Sep 17 00:00:00 2001 From: Chris Mason Date: Tue, 25 May 2010 10:12:41 -0400 Subject: Btrfs: don't walk around with task->state != TASK_RUNNING Yan Zheng noticed two places we were doing a lot of work without task->state set to TASK_RUNNING. This sets the state properly after we get ready to sleep but decide not to.
