* 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] compat: sock: Remove ->sendpage*() in favour of
|
|
sendmsg(MSG_SPLICE_PAGES)
|
|
|
|
See also upstream Linux kernel commits
|
|
dc97391e6610 ("sock: Remove ->sendpage*() in favour of sendmsg(MSG_SPLICE_PAGES)")
|
|
eeac7405c735 ("drbd: Use sendmsg(MSG_SPLICE_PAGES) rather than sendpage()")
|
|
4b9c2edaf728 ("drbd: swap bvec_set_page len and offset")
|
|
|
|
Original message:
|
|
|
|
Remove ->sendpage() and ->sendpage_locked(). sendmsg() with
|
|
MSG_SPLICE_PAGES should be used instead. This allows multiple pages and
|
|
multipage folios to be passed through.
