Using a failpoint, force the completion step of timeline ancestor detach to fail after reparenting a single timeline.
Retrying should try reparenting until all reparentings are done, all the time blocking gc.
Using a failpoint, force the completion step of timeline ancestor detach to
fail after reparenting a single timeline.
Retrying should try reparenting until all reparentings are done, all the
time blocking gc even across restarts (first round).
A completion failpoint is used to inhibit completion on second to last
round.
On last round, the completion uses a path where no reparentings can happen
because original ancestor is deleted, and there is a completion to unblock
gc without restart.
