SubjectRe: [Bug #11954] sysprof tracer ABI regression in 2.6.28rc1

to avoid situations like this, it would be nice to print out the
format string itself in the trace header, in printf format string
style. That way if there's a trivial expansion in trace format, it can
be detected (and even followed) by user-space - without some ugly
version based API.
