From e57d143091f1c0b1a98140a4d2e63e113afb62c0 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Thu, 8 Aug 2019 08:47:14 +0200 Subject: mutex: Fix up mutex_waiter usage The patch moving bits into mutex.c was a little too much; by also moving struct mutex_waiter a few less common CONFIGs would no longer build.
