This takes too long time to be an 'auto' test, it runs for 20min on my
test vm and is still running, I think I have to kill it manually.

I noticed that generic/52[12] run long time fsx tests, and they are in
'soak long_rw' groups, perhaps this one fits there as well? And maybe
'stress' group too.

Thanks,
