From 172124e220f1854acc99ee394671781b8b5e2120 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Thu, 4 Jun 2009 22:34:44 +0200 Subject: [PATCH] Revert "block: implement blkdev_readpages" This reverts commit db2dbb12dc47a50c7a4c5678f526014063e486f6. It apparently causes problems with partition table read-ahead on archs with large page sizes. Until that problem is diagnosed further, just drop the readpages support on block devices.
