SubjectRe: [PATCHv2][SMB3] Add kernel trace support
Fair enough.

Onto a second point then, for future patches.

There are a lot of places where we do not (yet) pass a tcon as argument.
Can we make a policy decision to mandate that every tracepoint MUST
log tid, sid?

And thus, if you need a new tracepoint in a function where tcon is not
available you then first
have to do the plumbing to pass the tcon all the way down to the tracepoint?

Ideally we should pass tcon into any and every leaf function for
tracepoints as well as debug logging.
