As we have blktests[1] now, I think this may fit in blktests better?
Hi Eryu,
Do you think test cases which use scsi_debug module should be moved into
blktests?
(e.g. generic/108, generic/349, generic/350, generic/351)
I don't think they need to be moved to blktests. Most other tests that
take use of scsi_debug are for filesystem testing, e.g. generic/108.
generic/349 generic/35[01] are a bit special, they were there before
blktests was announced available, so they're in a special blockdev group
and not in the auto group. If Omar agrees, I think they can be ported to
blktests.
Hi Eryu,
Thanks for your explanation, and i will try to send it to blktests.
Thanks,
Xiao Yang
I agree, the three tests Eryu mentioned and this new test would be a
good fit for blktests. Let me know if you need any help porting, things
are a little different from xfstests.
Hi Omar,
With gcc v4.4.7 on RHEL6, i got the following compiler error:
----------------------------------------------------------------------------------------------------------------------

It seems that __atomic_* functions are not available, and could you tell
me how to fix
the compiler error?
Thanks,
Xiao Yang
