[sheepdog] [PATCH v2 0/4] sheepdog: support online snapshot from qemu-img

[MORITA Kazutaka]

v2:
 - rename reload_vdi_obj to reload_inode and use it from
   sd_snapshot_goto (Yuan)
 - use g_free instead of free (Stefan)
 - fix typo in the comment (Stefan)
 - add coroutine_fn marker to resend_aioreq

Currently, we can take sheepdog snapshots of running VMs only from the
qemu monitor.  This series allows taking online snapshots from
qemu-img.

The first two patches prepare for the thrid patch.

MORITA Kazutaka (4):
  sheepdog: cleanup find_vdi_name
  sheepdog: add SD_RES_READONLY result code
  sheepdog: add helper function to reload inode
  sheepdog: resend write requests when SD_RES_READONLY is received
