The seven patches in this series is what I came up with while
reviewing and testing the dm-mpath single queue and multiqueue code.
It would be appreciated if these patches would be considered for
inclusion in the upstream kernel.
This series seems like it is not a product of need. But that of changes
that fell out from code review.
If not, what test was failing that now passes with this patchset?
Hello Mike,
Without this patch series I see sporadic I/O errors when running I/O on
top of dm-mq-on-mq. With this patch series my dm-mq-on-mq tests pass.
However, I still see sporadic I/O errors being reported when I run I/O
on top of dm-sq-on-mq and very sporadic I/O errors with my dm-sq-on-sq
tests. It is not yet clear to me what is causing these I/O errors but
it's probably something in either the dm core or the dm-mpath driver. My
tests scripts are available at https://github.com/bvanassche/srp-test in
case you would like to have a look.
Bart.
