It was certainly not meant to derail the discussion about the merits of utrace as a useful cleanup API in its own right, but rather to be an example of what kinds of things become straightforward in its presence.

Less passionate analysis would identify a long history of contribution by the the greater affiliated team, including via merged code and by and passing on requirements and experiences. We have been trying to share as much as you have been willing to take. While systemtap's current codebase may not (and need not) have a future inside the kernel, chances are good that improvements in common infrastructure will allow systemtap to shrink and change enough that the question becomes moot. - FChE -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
