Subject: [patch 6/6] zfcp: Remove duplicated unlikely() macros.
Date: Thu, 21 Aug 2008 13:43:37 +0200	[thread overview]
Message-ID: <20080821114559.686444000@de.ibm.com> (raw)
In-Reply-To: 20080821114331.148204000@de.ibm.com

[-- Attachment #1: 706-zfcp-unlikely.diff --]
[-- Type: text/plain, Size: 4973 bytes --]

From: Hirofumi Nakagawa <hnakagawa@miraclelinux.com>

Some drivers have duplicated unlikely() macros. IS_ERR() already
has unlikely() in itself. This patch cleans up such pointless
codes although there is no real effect on the kernel's behaviour.
