Peter Anvin" <hpa@...or.com>, Alexander Viro <viro@...iv.linux.org.uk> Cc: linux-fsdevel@...r.kernel.org, x86@...nel.org, linux-kernel@...r.kernel.org, Peter Zijlstra <peterz@...radead.org>, Scott J Norton <scott.norton@...com>, Douglas Hatch <doug.hatch@...com>, Waiman Long <Waiman.Long@....com> Subject: [RFC PATCH 2/3] lib/list_batch, x86: Enable list insertion/deletion batching in x86-64 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.
