[PATCH v3 4/4] replication: Remove workaround |
Date: |
Wed, 7 Jul 2021 20:15:52 +0200 |
Remove the workaround introduced in commit
6ecbc6c52672db5c13805735ca02784879ce8285
"replication: Avoid blk_make_empty() on read-only child".
It is not needed anymore since s->hidden_disk is guaranteed to be
writable when secondary_do_checkpoint() runs. Because replication_start(),
_do_checkpoint() and _stop() are only called by COLO migration code
and COLO-migration doesn't inactivate disks.
