[PATCH 0 of 3 v2] PV-GRUB: add support for ext4 and btrfs
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

[PATCH] Btrfs: fix broken nocow after balance
Balance will create reloc_root for each fs root, and it''s going to
record last_snapshot to filter shared blocks. The side effect of
setting last_snapshot is to break nocow attributes of files.
So it turns out that checking last_snapshot does not always ensure that
a node/leaf/file_extent is shared.
That''s why shared node/leaf needs to search extent tree for number of

[patch 00/65] Error handling patchset v3
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
