Hi,

A release in the 8.4 branch is really overdue. Please try it out, and
verify that you preferred 8.4 bug has been fixed in the meantime.

Please note: This is a release candidate, not intended for production.
Please help with testing!

8.4.2rc1 (api:genl1/proto:86-100)
--------
 * Fixed a write ordering problem on SyncTarget nodes for a write to a block
   that gets resynced at the same time. The bug can only be triggered with a
   device that has a firmware that actually reorders writes to the same
   block (merged from 8.3.13)
 * Fixed a potential deadlock during restart of conflicting writes
 * All fixes that went into 8.3.13
 * Removed a null pointer access when using on-congestion policy on a
   diskless device
 * In case of a graceful detach under IO load, wait for the outstanding
   IO. (As opposed to aborting IOs as a forcefully detach does)
 * Reinstate disabling AL updates with invalidate-remote (8.4.0 regression)
 * Reinstate the 'disk-barrier no', 'disk-flushes no', and 'disk-drain no'
   switches (8.4.0 regression)
 * Backported the request code from DRBD-9. Improves handling of many corner
   cases.
 * Support FLUSH/FUA bio flags
 * Made the establishing of connections faster
 * New option 'al-updates no' to disable writing transactions into the
   activity log. It is use full if you prefer a full sync after a primary
   crash, for improved performance of a spread out random write work load
 * Expose the data generation identifies via sysfs
 * "--stop" option for online verify to specify a stop sector
