Subject: [PATCH v3 11/11] ntfs: remove (un)?likely() from IS_ERR() conditions
Date: Thu, 29 Aug 2019 19:50:25 +0300	[thread overview]
Message-ID: <20190829165025.15750-11-efremov@linux.com> (raw)
In-Reply-To: <20190829165025.15750-1-efremov@linux.com>

"likely(!IS_ERR(x))" is excessive. IS_ERR() already uses
unlikely() internally.
