We're most likely to end up in this function when faulting is allowed, so predict_true is the better option. --- sys/powerpc/powerpc/trap.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/sys/powerpc/powerpc/trap.c b/sys/powerpc/powerpc/trap.c index d919b7715664..203d270a504b 100644 --- a/sys/powerpc/powerpc/trap.c +++ b/sys/powerpc/powerpc/trap.c @@ -794,7 +794,7 @@ trap_pfault(struct trapframe *frame, bool user, int *signo, int *ucode) return (true); #endif - if (__predict_false((td->td_pflags & TDP_NOFAULTING) == 0)) { + if (__predict_true((td->td_pflags & TDP_NOFAULTING) == 0)) { /* * If we get a page fault while in a critical section, then * it is most likely a fatal kernel page fault.
