From f7d61dcd6873c49bcc42be2caa2af1c2511aa915 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Tue, 15 Nov 2011 09:31:24 -0500 Subject: Btrfs: clear pages dirty for io and set them extent mapped When doing the io_ctl helpers to clean up the free space cache stuff I stopped using our normal prepare_pages stuff, which means I of course forgot to do things like set the pages extent mapped, which will cause us all sorts of wonderful propblems.
