Hi Christoph,
Are you perhaps referring to test block/027? It passes in my test-VM
with Jens' for-next branch and the following blktests config file:
TEST_DEVS=(/dev/vdb)
It seems to me that the entire patch series is still present on Jens'
for-next branch (commit 05ab4411bd69b809aa62c774866ce0b9be072418)?
Thanks,
Bart.
