Avoid getting work queue splats in the system journal by moving
client-side RPC/RDMA transport tear-down into a background process.
I've done some testing of this series, now looking for review
comments.
How to make tests with nfs && rdma? Can you provide some steps or tools?
We are building NFS tests into kdevops:
https://github.com/linux-kdevops/kdevops.git
and there is a config option to use soft iWARP instead of TCP.
Thanks a lot. It is interesting. Have you made tests with RXE instead of
iWARP?
If yes, does nfs work well with RXE? I am just curious with nfs && RXE.
Normally nfs works with TCP. Now nfs will use RDMA instead of TCP.
The popular RDMA implementation is RoCEv2 which is based on UDP protocol.
So I am curious if NFS can work well with RXE (RoCEv2 emulation driver)
or not.
If the user wants to use nfs in his production hosts, it is possible
that nfs will work with RoCEv2 (UDP).

kdevops includes workflows for fstests, Mora's nfstest, the
git regression suite, and ltp, all of which we use regularly
to test the Linux NFS client and server implementations.
I am interested in nfs && rdma.
Thanks,
