Hi Kevin,

Thanks for accepting the series.  There is one more piece of breakage
that Chris Krumme found in block.c:find_image_format() in the original
patch.  Please apply the patch to add the missing bdrv_delete() for the
SG_IO case below.

Thanks for pointing this out Chris!

Best,

[PATCH] [block]: Add missing bdrv_delete() for SG_IO BlockDriver in find_image_format()

This patch adds a missing bdrv_delete() call in find_image_format() so that a
SG_IO BlockDriver properly releases the temporary BlockDriverState *bs created
from bdrv_file_open()

Right, thanks for the fix.  I've applied it to the block branch.
