v3:
- Rebase to master after majority of Fabiano's series merged
- Dropped patch 2: "migration: Let migrate_set_error() take ownership"
(When looking again, I'm not happy with neither that of my patch nor
current code. But in that case I prefer change nothing rather than
changing from one ugly to another)
- Dropped a few Fabiano's R-b due to either rebase (return path thread now
is recycled when pausing postcopy) or additional error_free() after I
dropped patch 2
v1: https://lore.kernel.org/r/20230829214235.69309-1-peterx@redhat.com
v2: https://lore.kernel.org/r/20230912222145.731099-1-peterx@redhat.com
This series allow better error handling in the postcopy return path thread,
so that we'll start to store the errors in MigrationState and can be seen
from query-migrate later, comparing to before where we do error_report()
and never remember the error.
Meanwhile, it allows double-failures to happen during postcopy recovery,
IOW, one can fail again right during RECOVER phase on both sides, even if
RECOVER phase should be an extremely small window.
Please have a look, thanks.
