Subject: [patch] NVMe: Precedence error in nvme_pr_clear()
Date: Tue, 03 Nov 2015 19:50:49 +0000	[thread overview]
Message-ID: <20151103195049.GA17238@mwanda> (raw)
In-Reply-To: <20151103153958.GH13904@localhost.localdomain>

The original code is equivalent to:

	u32 cdw10 = (1 | key) ? 1 << 3 : 0;

But we want:

	u32 cdw10 = 1 | (key ? 1 << 3 : 0);

Fixes: 1d277a637a71: ('NVMe: Add persistent reservation ops')
