Subject: [PATCH] irq_work: Don't reinvent the wheel but use existing llist API
Date: Tue, 31 Oct 2017 02:46:54 +0100 [thread overview]
Message-ID: <1509414414-14987-1-git-send-email-frederic@kernel.org> (raw)
From: Byungchul Park <byungchul.park@lge.com>
Although llist provides proper APIs, they are not used. Make them used.
