I've hacked together some improvements to the tracepoints that record
server callback and lease management activity. I'm interested in
review comments and testing. I'm sure I've missed your favorite edge
case, so please let me know what it is!
Changes since v2:
- Postponed '%.s' fix-ups so the series applies to v5.13-rc1 as-is
- Split up the nfsd_clid_expired tracepoint
- Add nfserr and cp_count to the nfsd_cb_offload tracepoint
Changes since RFC:
- Rebased firmly on v5.13-rc1
- Re-organized the SETCLIENTID/EXCHANGE_ID tracepoints
- Fixed/replaced the use of '%.*s'
- Re-ordered the series so those fixes come first
