[PATCH v2 0/8] nfs: few fixes and enhancements

From: Chuck Lever <[email protected]>

Original cover:

In prepration for talking about NFS tests at the MSST conference today
I figured I'd give a run to all NFS tests. I ran out of time but at
least this plumbed quite a bit of the stuff to get some results out.

The iSCSI stuff is likely not correct, and can be dropped. So, feel
free to take in only what makes sense and drop whatever silly thing
you see.

Updates:

I'm reposting because, strangely, I never received these patches in
my inbox. I pulled this series from lore using "b4 am" so we can
keep reviewing.

For "devconfig: exclude nfsd from journal upload client
configuration", I wonder if instead of "nfsd", the new checks
should look for the "service" group, which usually includes nfsd,
the SMB server, the iscsi target, and the Kerberos KDC. Any opinion
on that?

I've dropped the iSCSI-specific changes. Except for a couple of
nits, the remaining patches look great to me.

The original idea for pNFS block testing was that a separate iSCSI
target was to be set up: either it is outside the kdevops test
network, or it is enabled by setting CONFIG_KDEVOPS_ENABLE_ISCSI.
Then change the kdevops nfsd server to use that iSCSI target by
changing the "Persistent storage for exported file systems" setting
to "iSCSI".

It's easier overall if the iSCSI target host is separate from the
kdevops nfsd host. iSCSI loopback is not as performant and is less
reliable, I've found -- and maybe not supported on every Linux
distribution we want to run kdevops on, IIRC.

The gitr, nfstest, and pynfs workflows should all be able to use
pNFS block, and indeed the latter two have additional tests
especially for pNFS block layout. So fstests-specific pNFS block
patches don't seem right to me.

Luis, if you believe I missed something and need to revisit one or
more of the patches I've left out, please don't hesitate to bring
it up.
