nvme/001 failed about blktests HOT 7 CLOSED

Thanks for the report.

It looks like the output filter work correctly.
It has actually several problems:

• it doesn't normalize the white space between the PID and the CPU#
• It doesn't account for eventual preempts (might be interesting to investigate why you have it set here)
• It doesn't account for slba's != 0

from blktests.

I think the filter should be:

sed -r -e  's/dd-[0-9]+/dd-XXX/' \
    -e 's/X\s+\[/X   [/' \
    -e 's/\[[0-9]+\]/[XXX]/' \
    -e 's/[0-9\.]{4}\s+/....    /' \
    -e 's/[0-9]+\.[0-9]+/X.XXXXXX/' \
    -e 's/qid=[0-9-]+/qid=X/' \
    -e 's/nsid=[0-9-]+/nsid=X/' \
    -e 's/cmdid=[0-9-]+/cmdid=X/' \
    -e 's/slba=[0-9]+/slba=X/'
