[Debian-ha-maintainers] Bug#939788: drbd-utils: Invalid argument with kernel 5.2

[Russell Mosemann]

Package: drbd-utils
Version: 9.5.0-1+b1
Severity: important

Dear Maintainer,

   * What led up to the situation?
Installed kernel 5.2. Works fine with 4.19.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
drbd fails to mount devices with "Invalid argument." See the follwoing links.

https://bugzilla.kernel.org/show_bug.cgi?id=204623

There is nothing in Debian, not even unstable, that fixes this problem.
Any Debian site using drbd is dead in the water with kernel 5.2. Please
provide the fix at the links above.
