This series of patches is aimed to prevent usage of image
file by different qemu instances. In case we are the first
instance, and option lock is lockfile, - we lock the image file,
and if check option is on, we check the file and fix it if
nessecary. If one of this two ops fails - the image is closed
with the error.
Patchset is not polished at all! Sent for a discussion as an alternative
approach.
