Cherry-picked the relevant common bits from commit 70d41e17164b in Josef Bacik's fstests tree (https://github.com/josefbacik/fstests). Quoting from Josef's commit message: This patch adds the supporting code for using the dm-log-writes target. The dmlogwrites code is similar to the dmflakey code, it just gives us functions to build and tear down a dm-log-writes target. We add a new LOGWRITES_DEV variable to take in the device we will use as the log and add checks for that. [Amir:] - Removed unneeded _test_falloc_support - Moved _require_log_writes to dmlogwrites - Document _require_log_writes - Address review comments by Eryu Guan Cc: Josef Bacik <jbacik@fb.com> Signed-off-by: Amir Goldstein <amir73il@gmail.com> Reviewed-by: Eryu Guan <eguan@redhat.com> Signed-off-by: Eryu Guan <eguan@redhat.com>
