...eliable, the virtio_net driver doesn't disable callbacks on transmit so the START_USE/END_USE debugging reentrance protection can be easily tripped even on UP.

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.

Hi Rusty, I hit a bug in virtio_ring.c:218 when I was stressing virtio_net using kvm with -smp 4. static void vring_disable_cb(struct virtqueue *_vq) { struct vring_virtqueue *vq = to_vvq(_vq); START_USE(vq); --> BUG_ON(vq->vring.avail->flags & VRING_AVAIL_F_NO_INTERRUPT); vq->vring.avail->flags |= VRING_AVAIL_F_NO_INTERRUPT;

Hi, For a medium term project, I''m thinking of working on transparent compression for Btrfs. Please give any hints and comments on how we would want to go about this, the features we would like to have and some common pitfalls to avoid. Is looking at how it''s done in Reiser4, a good idea ? Can we allow the compression algorithm be configurable on a per file basis, may be
