[DRBD-announce] drbd-9.1.7-rc.1

Hello,

I am starting the drbd-9.1.7 release cycle early. This time, the most
relevant change is fixing IO request unfreezing on diskless nodes. It
turned out this was broken, now there is a test that examines all these
cases. A number of bugs got fixed in this area.
These are important fixes for users that have "on-no-quorum suspend-io" in
their configs.

At the moment, this is a release candidate. Please give it a try.

9.1.7-rc.1 (api:genl2/proto:110-121/transport:17)
--------
 * fix for a "forgotten" resync after IO was suspended due to lack of quorum
 * refactored IO suspend/resume fixing severl bugs; the worst one could
   lead to premature request completion
 * disable discards on diskless if diskful peers do not support it
 * make demote to secondary a two-phase state transition; that guarantees
that
   after demotion, DRBD will not write to any meta-data in the cluster
 * enable "--force primary" in for no-quorum situations
