Commit Message

Kevin Wolf March 9, 2021, 12:18 p.m. UTC 
bdrv_close_all() asserts that no jobs are running any more, so we need
to cancel all jobs first to avoid failing the assertion.

Fixes: b55a3c8860b763b62b2cc2f4a6f55379977bbde5
Reported-by: Nini Gu <ngu@redhat.com>

$seq is a bit of a misnomer, now, but such is life.
