Hi- Jeff noticed my XDR tracepoints branch was getting stale. I've rebased it on latest stable (v5.19). https://git.kernel.org/pub/scm/linux/kernel/git/cel/linux.git/log/?h=topic-xdr-tracepoints This adds nfsd_xdr and lockd_xdr subsystems. When enabled, they record the arguments and results of each RPC request (NFSv3, NFS3ACL, NFSv4, and NLM). It's noisy as hell, but I've posted it for people to try out or even use to solve their issues. Comments and opinions welcome. -- Chuck Lever
