Hi,
while testing the userspace scrub updates, I've found lots of parent
transid verify failures (see below) that are likely unrelated to the
userspace patches.
The filesystem was freshly created with raid10/raid10 profiles on 4x10G
partitions (sda5...8) and there was
fs_mark -D 5000 -S0 -n 100000 -s 0 -L 200 -d /mnt/a1/scratch/0
(16x -d ...)
running when I started scrub on /dev/sda5, ran status a few times and
then ran scrub cancel.
Cancel hung
