From b037b09b9058d84882fa2c4db3806433e2b0f912 Mon Sep 17 00:00:00 2001 From: Andy Lutomirski Date: Fri, 3 Jul 2020 10:02:58 -0700 Subject: x86/entry: Rename idtentry_enter/exit_cond_rcu() to idtentry_enter/exit() They were originally called _cond_rcu because they were special versions with conditional RCU handling. Now they're the standard entry and exit path, so the _cond_rcu part is just confusing. Drop it. Also change the signature to make them more extensible and more foolproof. No functional change -- it's pure refactoring.
