With the ATI bug I was hitting earlier fixed, only my btrfs partition continues to show high cpu usage for some operations. Rsync, git pull, git checkout and svn up are typicall operations which trigger the high cpu usage. As an example, this perf report is from using git checkout to change to a new branch; the change needed to checkout 208 files out of about 1600 total files. du(1) reports

Hi, Here''s an implementation of NFS support for btrfs. It does not work in one particular case as described in http://www.mail-archive.com/linux-btrfs@vger.kernel.org/msg00298.html. This uses the btrfs_iget helper introduced previously. Comments ? --- Signed-off-by: Balaji Rao <balajirrao@gmail.com> diff -r 3f0eee804974 Makefile --- a/Makefile Thu Jun 26 10:34:20 2008 -0400
