* Changelog from Linbit:
9.1.23 (api:genl2/proto:86-101,118-121/transport:18)
--------
* Fix a corner case that can happen when DRBD establishes multiple
connections in parallel, which could lead one connection to end up in
an inconsistent replication state of WFBitMapT/Established
* Fix a corner case in which a reconciliation resync ends up in
WFBitMapT/Established
* Restrict protocol compatibility to the most recent 8.4 and 9.0 releases
* Fix a corner case causing a module ref leak on drbd_transport_tcp;
if it hits, you can not rmmod it
* rate-limit resync progress while resync is paused
* resync-target inherits history UUIDs when resync finishes,
this can prevent unexpected "unrelared data" events later
* Updated compatibility code for Linux 6.11 and 6.12
* remove patches which already included in the new version:

Subject: [PATCH 26/32] compat: test and patch for __counted_by
|
|
|
|
Unfortunately, the "attribute name" variable type only works with very
|
|
recent coccinelle versions (>=1.1.1). So add a hint about that in the
|
|
README.
