drbd-9.2.16-rc.1 and drbd-9.3.0-rc.5

[Philipp Reisner]

Hello drbd users,

The next releases are coming soon. Today I have the honour to announce
the availability of release candidate 1 for drbd-9.2.16 and
drbd-9.3.0-rc.5. The latter is already at 5, since we did some internal
release candidates. This time it looks good.
Regarding the fixes, everything is minor and boring.

drbd-9.3 is where the exciting new features are. This time, it got
support for tunable bitmap granularity and for disabling the
change-tracking bitmap entirely.

Please help test the release candidates. I plan to do the final releases
in one week if nobody finds a showstopper.


9.2.16-rc.1 (api:genl2/proto:86-101,118-122/transport:19)
--------
 * Do not trigger the OOM-killer when allocating a too-big dirty
   bitmap during attach; instead, fail the attach operation.
 * Do not flush half-created packets out while closing a connection
 * Fixed a bug that, in rare circumstances, when flapping between
   Ahead and resync, can lead to a divide by zero error.
 * Fixed a bug that caused DRBD to send too many P_PEERS_IN_SYNC
   packets when finishing a resync; on huge devices ( >10TB), that led
   to temporarily higher I/O latencies.
 * Fixed an unhandled corner case to automatically reintegrate an I/O
   frozen primary into a larger partition that created a newer data
   generation
 * Compatibility with Linux-6.17

   block size
