Cool!
When I tried testing it on x86 against recent mainline, I got:
"WARNING: WARNING: Bad or missing .orc_unwind table. Disabling unwinder."
But when I tested on recent mainline without your patches:
4597fcff0704 "Merge tag 'for-4.18/dm-changes-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm"
I get the same warning. Trying again on today's mainline, but in the meantime, is anyone else seeing this?
Thanx, Paul
