From ba69994a40b242bef26ab2683ea84aa29e2e429f Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Sun, 3 Nov 2013 19:06:40 +0200 Subject: [PATCH] Btrfs: fix __btrfs_start_workers retval __btrfs_start_workers returns 0 in case it raced with btrfs_stop_workers and lost the race. This is wrong because worker in this case is not allowed to start and is in fact destroyed. Return -EINVAL instead.
