What about metadata_csum? Seems it's not used in the actual resize test.
Meant to delete it?

Hmm, how do we tell if it's a test failure or lack of kernel support?
How about adding an extra argument to ext4_online_resize to indicate
that this is a test run, so it checks resize2fs output to see if the
failure is really due to lacking support in kernel. Otherwise we treat
all resize2fs failures as bugs.
e.g. resize2fs prints:
"resize2fs: Operation not supported While checking for on-line resizing support"
Thanks,
Eryu
Add tests to verify Ext4 online resizing feature with bigalloc feature
enabled. We test various resizing scenarios with different cluster
sizes.

Thanks for all the revisions! I made some minor edits and queued it for
next release. Please see below.

No need to call _fail here, _create_loop_device already did that.

I changed this to let resize2fs dump output to a tmp file, saving
multi-line outputs into a variable would cause subtle problems that are
hard to find/debug. e.g. echoing a such variable to a pipe without
proper quotes would change the output in subtle ways, and we did hit
such problems before.

Then grep the tmp file and append it to $seqres.full.
