[PATCH] mutex subsystem, add typecheck_fn(type, function)
add typecheck_fn(type, function) to do type-checking of function pointers. Modified-by: Ingo Molnar <mingo@elte.hu> (made it typeof() based, instead of typedef based.) Signed-off-by: Chuck Ebbert <76306.1226@compuserve.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
