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 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
In fact I'd like to submit the first 5 patches for v5.13-rc.
