I just got this iotest 260 failure processing an
unrelated merge on my x86-64 Ubuntu box. I assume
it's an intermittent (have just kicked off a retry) but
post the backtrace in case it's of interest:

I hope it’s intermittent, although I presume it might not be.
In any case, I’ve recently sent a series to address this kind of issue
(https://lists.nongnu.org/archive/html/qemu-block/2019-10/msg00561.html)

It has indeed failed again. Is there some way to get the
build to pick a shorter test directory name, or to get
'make check' to skip the iotests, so I can proceed with
testing until that fix lands?

Yes, you can set the $TEST_DIR environment variable to a shorter scratch
path.

Thanks, that works. It turns out that it wasn't "an unrelated
merge", I was confused. It's a merge that adds iotest 260,
which is why I hadn't seen the failure before.
