From e99761514999f64aff1985460967f93d9e8417f4 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Thu, 11 Oct 2012 15:53:56 -0400 Subject: Btrfs: only log the inode item if we can get away with it Currently we copy all the file information into the log, inode item, the refs, xattrs etc. Except most of this doesn't change from fsync to fsync, just the inode item changes. So set a flag if an xattr changes or a link is added, and otherwise only log the inode item.
