[PATCH v2 0/2] mirror: Fix hang (operation waiting for itself/circular dependency)
Thu, 26 Mar 2020 16:36:26 +0100
The recent fix didn't actually fix the whole problem. Operations can't
only wait for themselves, but we can also end up with circular
dependencies like two operations waiting for each other to complete.
This reverts the first fix and implements another approach.
- Mark active mirror operations as in-flight, too

Revert "mirror: Don't let an operation wait for itself"
mirror: Wait only for in-flight operations
