Thanks for the patch, but I'm not sure I entirely follow.
What "issues with data inflation because of invalid input data stream
for zlib decompression" were there and how do they relate to lack of
space on /var/lib/xen ?
Is this just for the situation where the dom0 filesystem hasn't enough
space to contain the uncompressed version of the domU kernel and
initrd which are to be loaded ?
Your patch just raises an error. Why does the situation in which the
patch is needed not already raise an appropriate error ? Perhaps it
would be better to arrange that it does.
