From mboxrd@z Thu Jan 1 00:00:00 1970 Subject: earlier allocation of order 0 pages in __alloc_pages From: Rohit Seth Content-Type: text/plain Date: Wed, 28 Sep 2005 14:18:36 -0700 Message-Id: <1127942316.5046.37.camel@akash.sc.intel.com> Mime-Version: 1.0 Content-Transfer-Encoding: 7bit Sender: owner-linux-mm@kvack.org Return-Path: To: linux-kernel@vger.kernel.org, linux-mm@kvack.org List-ID: I'm wondering if it is a good idea in __alloc_pages to first try to see if a order 0 request can be serviced by cpu's pcp before checking the low water marks for the zone. The is useful if a request can be serviced by a free page on the pcp then there is no reason to check the zone's limits. This early allocation should be without any replenishing of pcps from zone free list thanks, -rohit -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
