Actually, it might not have been. I seem to recall someone on the panel
describing utrace as changing code "all over the kernel", which would be
different (and more mistaken). I guess once the LF video gets released,
our memories can be checked.

(I wish this sort of pedantry were not necessary, but words from important
people carry weight, so they had better be correct.)

tracehook.h was one of the early parts of utrace that got merged.

utrace was merged in -mm for a while and the results were bad enough that it got yanked at least once.

As for the utrace ftracer. utrace predates ftrace by several years and it certainly did not exist before it was merged.
