From: Mel Gorman Date: Tue, 16 Oct 2007 08:25:53 +0000 (-0700) Subject: Group high-order atomic allocations X-Git-Tag: v2.6.24-rc1~1136 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e010487dbe09d63cf916fd1b119d17abd0f48207;p=pandora-kernel.git Group high-order atomic allocations In rare cases, the kernel needs to allocate a high-order block of pages without sleeping. For example, this is the case with e1000 cards configured to use jumbo frames. Migrating or reclaiming pages in this situation is not an option. This patch groups these allocations together as much as possible by adding a new MIGRATE_TYPE. The MIGRATE_HIGHATOMIC type are exactly what they sound like. Care is taken that pages of other migrate types do not use the same blocks as high-order atomic allocations.
