From 43d2d52d704e025518d35c3079fcbff744623166 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Sun, 15 Aug 2021 23:28:33 +0200 Subject: [PATCH] locking/mutex: Move the 'struct mutex_waiter' definition from to the internal header Move the mutex waiter declaration from the public header to the internal kernel/locking/mutex.h header. There is no reason to expose it outside of the core code.
