The only downside is that less callers will be visible. - -Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> ---- - mm/slub.c | 3 +++ - 1 file changed, 3 insertions(+) - ---- a/mm/slub.c -+++ b/mm/slub.c -@@ -4822,6 +4822,9 @@ static int alloc_loc_track(struct loc_tr - struct location *l; - int order; - -+ if (IS_ENABLED(CONFIG_PREEMPT_RT) && flags == GFP_ATOMIC) -+ return 0; -+ - order = get_order(sizeof(struct location) * max); - - l = (void *)__get_free_pages(flags, order); |
