[DRBD-announce] drbd-9.0.22-0rc1

Hi,

It is just a number of smaller bug-fixes. No single one that I want to point
out.

Please help testing this release candidate.

9.0.22-0rc1 (api:genl2/proto:86-116/transport:14)
--------
 * introduce locking to avoid connection retries when UUIDs or
   relevant flags change during the exchange of this data
 * improve serialization of events after losing a primary
 * fix a constraint in sanitize state that can cause a promote to be
   declined by some other node
 * fix a case of a false positive detection of a split-brain condition
 * allow a resync target to switch to the resync source with less
   bits out of sync
 * fix bitmap UUID after resync to use current UUID from self rather
   than sync source
 * fix pushing bitmap UUID into history when changed
 * fix regression introduced with 9.0.20, that can cause a missed
   resync after a reconciliation resync
 * fix regression introduced with 9.0.20, that can cause a missed
   resync after a promote on a diskless node
