[Qemu-devel] [PATCH 2/6] blkdebug: Factor out remove_rule()

[Kevin Wolf <kwolf@redhat.com>]

The cleanup work to remove a rule depends on the type of the rule. It's
easy for the existing rules as there is no data that must be cleaned up
and is specific to a type yet, but the next patch will change this.
