From f22f71322a18e90e127f2fc2c11cc2d5191bc4c6 Mon Sep 17 00:00:00 2001 From: Waiman Long Date: Thu, 22 Feb 2024 10:05:40 -0500 Subject: locking/rwsem: Make DEBUG_RWSEMS and PREEMPT_RT mutually exclusive The debugging code enabled by CONFIG_DEBUG_RWSEMS=y will only be compiled in when CONFIG_PREEMPT_RT isn't set. There is no point to allow CONFIG_DEBUG_RWSEMS to be set in a kernel configuration where CONFIG_PREEMPT_RT is also set. Make them mutually exclusive.
