Subject: [RFC PATCH 2/3] lib/list_batch, x86: Enable list insertion/deletion batching in x86-64
Date: Tue, 26 Jan 2016 11:03:38 -0500 [thread overview]
Message-ID: <1453824219-51437-3-git-send-email-Waiman.Long@hpe.com> (raw)
In-Reply-To: <1453824219-51437-1-git-send-email-Waiman.Long@hpe.com>
System with a large number of CPUs will benefit from the list batching
facility. This patch enables it for x86-64 as 32-bit i386 is not
likely to get much gain from it.
