drbd-9.2.16 and drbd-9.3.0-rc.6

[Philipp Reisner]

Dear DRBD-users,

Here is the drbd-9.2.16 final release. The bugs fixed in this release
are mostly exotic corner cases. One fix is that a fatal user error
causes the machine to enter an annoying out-of-memory condition in
previous DRBD releases.

The developers have switched their interest to the 9.3 branch. I want to
roll it out internally, following the so-called 'eat your own dog food'
strategy, before I declare it a final release. I plan to release 9.3.0
early next week.

9.2.16 (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 two 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 and 6.18-rc6

9.3.0-rc.6 (api:genl2/proto:86-101,118-123/transport:19)
--------
 * Implemented support for bitmap granularity between 4k and 1M,
   including exchanging bitmaps with peers with a different bitmap
   block size
 * Add support for omitting bitmap allocation for standalone devices
 * Explicit config option for drbd8-api-compatibility mode
 * Give filesystems mounted on DRBD a chance to bring their on-disk
   representations into a consistent state before suspending I/O.
 * Fixes for resync without replication
 * All fixes from 9.2.14, 9.2.15 and 9.2.16
 * Compatibility with Linux-6.17
