Hi, The following patches add support for ext4 and btrfs to PV-GRUB. These patches are taken nearly verbatim from those provided by Fedora and Gentoo. We''ve been using these patches for the PV-GRUB images available in EC2 for some time now with no problems. Changes from v1: - Makefile has been changed to check the exit code from patch - The btrfs patch has been rebased to apply

From: Anand <anand.jain@oracle.com> This patch adds creation-time to the snapshot list display, which would help user to better manage the snapshots when number of snapshots grow substantially. This patch is developed and on top of the send/receive btrfs and btrfs-progs repo at git://github.com/ablock84/linux-btrfs.git (send-v2) git://github.com/ablock84/btrfs-progs.git (send-v2)

After a reorganisation of patches, and sending a bunch of them to Chris, I''ve also updated the integration branch to match that. It''s available from: http://git.darksatanic.net/repo/btrfs-progs-unstable.git/ integration-20110630 The shortlog of 17 patches in this branch beyond the ones I''ve sent to Chris is below. Hugo.

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

Hi all - Here''s my current error handling patchset, against 3.1-rc8. Almost all of this patchset is preparing for actual error handling. Before we start in on that work, I''m trying to reduce the surface we need to worry about. It turns out that there is a ton of code that returns an error code but never actually reports an error. The patchset has grown to 65 patches. 46 of them
