From dc17ff8f11d129db9e83ab7244769e4eae05e14d Mon Sep 17 00:00:00 2001 From: Chris Mason Date: Tue, 8 Jan 2008 15:46:30 -0500 Subject: Btrfs: Add data=ordered support This forces file data extents down the disk along with the metadata that references them. The current implementation is fairly simple, and just writes out all of the dirty pages in an inode before the commit.
