From 8d07e8a5f5bc7b90f755d9b427ea930024f4c986 Mon Sep 17 00:00:00 2001 From: Joe Thornber Date: Tue, 6 May 2014 16:28:14 +0100 Subject: dm thin: allow metadata commit if pool is in PM_OUT_OF_DATA_SPACE mode Commit 3e1a0699 ("dm thin: fix out of data space handling") introduced a regression in the metadata commit() method by returning an error if the pool is in PM_OUT_OF_DATA_SPACE mode. This oversight caused a thin device to return errors even if the default queue_if_no_space ENOSPC handling mode is used. Fix commit() to only fail if pool is in PM_READ_ONLY or PM_FAIL mode.
