drbd/0012-drbd-Restore-DATA_CORKED-and-CONTROL_CORKED-bits.patch
heming zhao 6ee9ba5898 - Update DRBD version from 9.1.22 to 9.1.23 (boo#1234849)
* 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 12/20] drbd: Restore DATA_CORKED and CONTROL_CORKED bits
They were removed with 9072e1d1b6b3 in January 2022.
Since then, the CONTROL_CORKED mapped onto C_UNREGISTERED.
I think that had a negligible impact because C_UNREGISTERED indicates
if a connection was deleted before. It is no longer connected when it
is time to delete a connection. Therefore, the corking code can not
set that double-used bit.
The other user of C_UNREGISTERED is when iterating over connections. A
wrongly set C_UNREGISTERED causes another iteration over the
connections list - no further harm.
Still, I am fixing this by allocating dedicated bits for corking in
the flags word.
