Hey Jens,

Would you be OK pulling the following branch:
git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/for-jens-4.19

which has a fix for flushing out persistent pages at a deterministic rate.

Thanks to the L1TF I did not manage to send this email until today - but
hopefully it won't be an issue to push it to Linus after -rc1?

It is based on your 'b86d865cb1ca (for-4.19/block) blkcg: Make blkg_root_lookup()
work for queues in bypass mode' branch.

Thank you!
