[PATCH 00/18] virtio and vhost-net performance enhancements
OK, here's a large patchset that implements the virtio spec update that I
sent earlier. It supercedes the PUBLISH_USED_IDX patches
I sent out earlier.
I know it's a lot to ask but please test, and please consider for 2.6.40 :)
I see nice performance improvements: one run showed going from 12
to 18 Gbit/s host to guest with netperf, but I did not spend a lot
of time testing performance,

[PATCH] btrfs-progs: avoid memory leak in btrfs_close_devices
Three kind of structures need to be freed on close:
* All struct btrfs_device managed by fs_devices
* The name field for each struct btrfs_device
* The above items for seed_devices

[PATCH 2/3] btrfs: remove unnecessary -ENOMEM BUG_ON check in extent-tree.c/btrfs_alloc_logged_file_extent
The memory allocation failure is BUG_ON in add_excluded_extent
(following the code path). No need to BUG_ON -ENOMEM inside
btrfs_alloc_logged_file_extent.

[PATCH v5 07/45] virtio: memory access APIs
virtio 1.0 makes all memory structures LE, so
we need APIs to conditionally do a byteswap on BE
architectures.
To make it easier to check code statically,
add virtio specific types for multi-byte integers
in memory.
Add low level wrappers that do a byteswap conditionally, these will be
useful e.g. for vhost. Add high level wrappers that
query device endian-ness and act accordingly.
