Subject: [PATCH nfs-utils 0/4] exports: add support for new riomode= and wiomode= export options
Date: Tue, 27 Oct 2026 12:50:22 -0400 [thread overview]
Message-ID: <20261027-master-v1-0-6f1f7a35a83b@kernel.org> (raw)
This patchset adds support for riomode= and wiomode= export options to
exportd and mountd. This is the companion patchset to [1].
The last patch in this adds a new nfsd-iomode-advisor script that
watches various stats on the server and advises the admin what mode to
use.
I consider the advisor optional as it was largely vibe-coded. I'm not
sure I'd trust its advice that far, but it's probably better than
guessing.
