Commit Message

Max Reitz Jan. 18, 2021, 10:57 a.m. UTC
Before this patch, test_block_commit() performs an active commit, which
under the hood is a mirror job.  If we want to test various different
block jobs, we should perhaps run an actual commit job instead.

Doing so requires adding an overlay above the source node before the
commit is done (and then specifying the source node as the top node for
the commit job).
