OK, that test again. I clearly need to invest time to making it run on my testbed. But that will take time (though hopefully I can cut through it tomorrrow).

Please feel free to test the 2 topmost commits I've staged in linux-next, via dm-4.16: https://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm.git/log/?h=dm-4.16 Mike -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
