[Sheepdog] [RFC PATCH v4 0/3] Sheepdog: distributed storage system for QEMU

[MORITA Kazutaka]

Hi all,

This patch adds a block driver for Sheepdog distributed storage
system.  Please consider for inclusion.

I applied comments for the 2nd patch (thanks Kevin!).  The rest
patches are not changed from the previous version.


Changes from v3 to v4 are:
 - fix error handling in bdrv_snapshot_goto.

Changes from v2 to v3 are:

 - add drv->bdrv_close() and drv->bdrv_open() before and after
   bdrv_snapshot_goto() call of the protocol.
 - address the review comments on the sheepdog driver code.

Changes from v1 to v2 are:

 - rebase onto git://repo.or.cz/qemu/kevin.git block
 - modify the sheepdog driver as a protocol driver
 - add new patch to call the snapshot handler of the protocol

Thanks,

Kazutaka
