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 25/32] drbd: Annotate struct fifo_buffer with __counted_by
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
As found with Coccinelle[1], add __counted_by for struct fifo_buffer.
