The two patches basically "fix" the usage of --offset in qemu-nbd.
The first patch fixes the issue that when offset is used the device size
is not updated and the client may request read/write beyond the end of
the file.
Second patch adds new argument --image-size to hard set the size of the
device. This is useful in combination with --offset when the image is
embedded in a file, but does not span to the end of the file.
Tomáš Golembiovský (2):
qemu-nbd: Shrink image size by specified offset
qemu-nbd: Add --image-size option
