From 2c0c9da02a2c4289350da6e54202a86602c0f926 Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Sun, 20 Jan 2013 15:57:57 +0200 Subject: [PATCH] Btrfs: fix "mutually exclusive op is running" error code The error code that is returned in response to starting a mutually exclusive operation when there is one already running got silently changed from EINVAL to EINPROGRESS by 5ac00add. Returning EINPROGRESS to, say, add_dev, when rm_dev is running is misleading. Furthermore, the operation itself may want to use EINPROGRESS for other purposes.
