Cover letter [Qemu-devel] [PATCH for 2.1 0/2] Fix commit of oversized layer

This fixes a regression in block-commit; if the top image is larger than the base image, we attempt to resize the base image. The regression is that we fail the image truncate operation, returning -EBUSY.

Jeff Cody (2):
block: check for RESIZE blocker in the QMP command, not
bdrv_truncate()
block: add qemu-iotest for resize base during live commit
