Hmm.
A less hacky patch might be to split up "sched.h" into multiple smaller things and at least get *part* of the way.
A lot of things want "struct task_struct" (and in some cases thread_info, but that's already split).
Much fewer care about the signal stuff.
And many things probably don't even need the task_struct definition, and might be perfectly happy with just function calls rather than having intimate knowledge of the structure layout and an inline function.
