How do you think about a wording variant like the following? If a call of the function “blkg_lookup_check” failed, release the previously allocated block group before jumping to the target “fail_unlock” in the implementation of the function “blkg_conf_prep”. Would you like to add the tag “Fixes” to the commit message? Regards, Markus
