This patch is causing generic/299 to loop forever for me. The problem
is that "fio" is too easy to match:
root@kvm-xfstests:~# pgrep fio
1407
root@kvm-xfstests:~# ps augxww | grep 1407
root 1407 0.0 0.0 0 0 ? S< 16:52 0:00
[dm_bufio_cache]
root 8386 0.0 0.0 2704 492 ttyS1 S+ 17:06 0:00 grep 1407
I'm currently a testing a patch which uses "pgrep -f $XFS_IO_PROG"
instead, but I'm a bit surprised no once else noticed this, I guess
people aren't building their xfstests test kernels with DM_SNAPSHOP or
DM_VERITY configured (either of which will seleect DM_BUFIO)?
