Re: [PATCH] avoid ifdefs in desc.h, getting rid of pack_ldt and pack_tss

Well, "no functional changes" is not quite the same thing as "no object code changes".

yeah, true, but the safest way to ensure no functional changes is to get identical object code. In sched-devel.git i include obj comparisons to cleanup patches as a self-assurance (and later bughunt helper) to make sure a cleanup is really just a cleanup.

Of course. "No object code changes" is a stronger statement, however, not all types of cleanups result in that.

It's highly useful when applied appropriately, though. In particular, the programmer should know when object code changes are expected.
