If tracing cleanups for trace_events.h are being done, perhaps
another bit of untidiness is the macro definition and uses of
__assign_str.

This isn't a tracing cleanup, but adding new functionality.

That said,

$ git grep -w -1 __assign_str include/trace/trace_events.h
include/trace/trace_events.h-
include/trace/trace_events.h:#undef __assign_str
include/trace/trace_events.h:#define __assign_str(dst, src)                                             \
include/trace/trace_events.h-   strcpy(__get_str(dst), (src) ? (const char *)(src) : "(null)");

Its definition has a semicolon as do most uses but a dozen handfuls of
other uses do not have a semicolon.  It'd be more consistent to add a
semicolon to the uses without them and when done treewide, then remove
the semicolon from the macro declaration.

I have no problem taking a clean up patch that adds semicolons to all
use cases of "__assign_str()" and ever remove the one from where it is
defined. As long as it doesn't break any builds, I'm fine with that.
