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

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

Hi gang, I was a little surprised to see that patch go by recently which fixed an endian bug. I went to see how sparse checking looked and it was.. broken. I got it going again in my Fedora environment. Most of the patches are just cleanups, but there *were* three real bugs lurking in all that sparse warning spam. So I maintain that it''s worth our time to keep it going and fix

This is a first draft of a subvolume quota implementation. It is possible to limit subvolumes and any group of subvolumes and also to track the amount of space that will get freed when deleting snapshots. The current version is functionally incomplete, with the main missing feature being the initial scan and rescan of an existing filesystem. I put some effort into writing an introduction into

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)

I''ve been working to try to improve the write-ahead log''s performance, and I found that the bottleneck addresses in the checksum items, especially when we want to make a random write on a large file, e.g a 4G file. Then a idea for this suggested by Chris is to use sub transaction ids and just to log the part of inode that had changed since either the last log commit or the last
