| From | Rasmus Villemoes <> | Subject | [PATCH v3 05/23] linux/printk.h: use DYNAMIC_DEBUG_BRANCH in pr_debug_ratelimited | Date | Sat, 10 Nov 2018 00:10:03 +0100 |
| |
pr_debug_ratelimited tests the dynamic debug descriptor the old-fashioned way, and doesn't utilize the static key/jump label implementation on architectures that HAVE_JUMP_LABEL. Use the DYNAMIC_DEBUG_BRANCH which is defined appropriately.
