[PATCH 5.15 196/690] SUNRPC: Tracepoints should display tk_pid and cl_clid as a fixed-size field

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Chuck Lever chuck.lever@oracle.com

[ Upstream commit b4776a341ec05e809d21e98db5ed49dbdc81d5d8 ]

For certain special cases, RPC-related tracepoints record a -1 as the task ID or the client ID. It's ugly for a trace event to display 4 billion in these cases.

To help keep SUNRPC tracepoints consistent, create a macro that defines the print format specifiers for tk_pid and cl_clid. At some point in the future we might try tk_pid with a wider range of values than 0..64K so this makes it easier to make that change.

RPC tracepoints now look like this:
