[DRBD-announce] drbd-9.0.29-0rc1 & drbd-9.1.2-rc.1

Hi,

here is the next release candidate for both of our branches. I promise to write
a bit more text for the final release, which will happen in one week if no show
stoppers are found.

This is a release candidate, please help testing it.

9.0.29-0rc1 (api:genl2/proto:86-120/transport:14)
--------
 * fix data corruption when DRBD's backing disk is a degraded Linux software
   raid (MD)
 * add correct thawing of IO requests after IO was frozen due to loss of quorum
 * fix timeout detection after idle periods and for configs with ko-count
   when a disk on an a secondary stops delivering IO-completion events
 * fixed an issue where UUIDs where not shifted in the history slots; that
   caused false "unrelated data" events
 * fix a temporal deadlock you could trigger when you exercise promotion races
   and mix some read-only openers into the test case
 * fix for bitmap-copy operation in a very specific and unlikely case where
   two nodes do a bitmap-based resync due to disk-states
 * fix size negotiation when combining nodes of different CPU architectures
   that have different page sizes
 * fix a very rare race where DRBD reported wrong magic in a header
   packet right after reconnecting
 * fix a case where DRBD ends up reporting unrelated data; it affected
   thinly allocated resources with a diskless node in a recreate from day0
   event
 * speedup open() of drbd devices if promote has not chance to go through
 * new option "--reset-bitmap=no" for the invalidate and invalidate-remote
   commands; this allows to do a resync after online verify found differences
 * changes to socket buffer sizes get applied to established connections
   immediately; before it was applied after a re-connect
 * add exists events for path objects
 * forbid keyed hash algorithms for online verify, csyms and HMAC base alg
 * following upstream changes to DRBD up to Linux 5.12 and updated compat
   rules to support up to Linux 5.12
