Subject: [PATCH 2/2] locking/mutex: Use mutex flags macro instead of hard code value
Date: Mon, 29 Jul 2019 16:22:58 +0530 [thread overview]
Message-ID: <1564397578-28423-2-git-send-email-mojha@codeaurora.org> (raw)
In-Reply-To: <1564397578-28423-1-git-send-email-mojha@codeaurora.org>
Let's use the mutex flag macro(which got moved from mutex.c
to linux/mutex.h in the last patch) instead of hard code
value which was used in __mutex_owner().
