The metadata space map has a simplified 'bootstrap' mode that is operational when extending the space maps. Whilst in this mode it's possible for some refcount decrement operations to become queued (eg, as a result of shadowing one of the bitmap indexes). These decrements were not being applied when switching out of bootstrap mode. The effect of this bug was the leaking of a 4k metadata block. This is detected by the latest version of thin_check as a non fatal error. Signed-off-by: Joe Thornber <ejt@redhat.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com> Cc: stable@vger.kernel.org |
