From f163f0302ab69722c052519f4014814bf10026a9 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Wed, 8 Jun 2022 16:40:21 +0200 Subject: context_tracking: Rename context_tracking_user_enter/exit() to user_enter/exit_callable() context_tracking_user_enter() and context_tracking_user_exit() are ASM callable versions of user_enter() and user_exit() for architectures that didn't manage to check the context tracking static key from ASM. Change those function names to better reflect their purpose.
