Hello James and Martin,
This short patch series fixes a deadlock that I ran into for the
first time several months ago but for which I had not yet had the
time to post a fix. As usual, feedback is appreciated.
First question would be why do we need to push highly dm specific
knowledge into block, like REQ_FAIL_IF_NO_PATH. Can't we just use
REQ_FAILFAST_X for this?
Also, I don't quite understand how you've configured multipath
underneath SCSI. I thought dm-mp always went on top?
Hello James,
dm-multipath was running on top of SCSI in my setup which means that at
least the patch description is wrong. Since it was some time ago that I
ran into this deadlock, I will check first whether I can still reproduce it.
Bart.
