Subject: [PATCH 0/9 RFC v2] NFS sysfs scaffolding
Date: Fri, 21 Apr 2023 13:08:03 -0400 [thread overview]
Message-ID: <cover.1682096307.git.bcodding@redhat.com> (raw)
Here's another round of sysfs entries for each nfs_server, this time with a
single use-case: a "shutdown" toggle that causes the basic rpc_clnt(s) to
immediately fail tasks with -EIO. It works well for the non pNFS cases to
allow an unmount of a filesystem when the NFS server has gone away.
I'm posting to gain potential NACKing, or to be redirected, or to serve as
fodder for discussion at LSF.
I'm thinking I'd like to toggle v4.2 things like READ_PLUS in here next, or
other module-level options that maybe would be useful per-mount.
Benjamin Coddington (9):
NFS: rename nfs_client_kset to nfs_kset

NFS: add a sysfs link to the lockd rpc_client
NFS: add a sysfs link to the acl rpc_client
NFS: add sysfs shutdown knob
NFS: Cleanup unused rpc_clnt variable
NFSv4: Clean up some shutdown loops
