Yes. Mechanically adding sched.h inclusions into .h files will cause
problems.

I've had decent success with this sort of thing by adding new,
finer-grained headers. Maybe include/linux/might_sleep.h would be a
good starting point to fix whatever it was that this fixed.


I think I'll make x86-include-linux-schedh-in-asm-uaccessh.patch,
tree-sweep-include-linux-schedh-for-might_sleep-users.patch and
sched-mark-should_resched-__always_inline.patch go away for now - I
need a mergeable tree, fast.
