From e1c4b7451e22f5b0a9fbccfa560ee7b80c35b8cd Mon Sep 17 00:00:00 2001 From: Chris Mason Date: Tue, 22 Apr 2008 13:26:46 -0400 Subject: Fix btrfs_get_extent and get_block corner cases, and disable O_DIRECT reads The generic O_DIRECT code assumes all the bios have the same bdev, which isn't true for multi-device btrfs.
