Hoping to keep the conflicts that it will cause to a minimum. ] With the rework of how the __string() handles dynamic strings where it saves off the source string in field in the helper structure[1], the assignment of that value to the trace event field is stored in the helper value and does not need to be passed in again.
Just curious if this could be done piecemeal by first changing the macros to be variadic macros which allows you to ignore the extra argument. The callers could then be modified in their separate trees. And then once all the callers have be merged, the macros could be changed to no longer be variadic.
