Remember that there's arch-dependent headers as well.  You may want this:

find include/ arch/FOO/include/ -type f | ....

for an appropriate value of FOO (usually x86 or arm, unless you're on a
powerpc or a sparc or one of the 23 other archs.. ;)

Won't  ake a difference for the specific case of kthread_run, but
you're not going to find something like vdso.h under include/
