The property size may be controlled by userspace, can be large (I've seen failure with order 4, i.e. 16 pages / 64 KB) and doesn't need to be physically contiguous.
I wonder if we should enforce some kind of reasonable limit on the blob size. Looks like we allow anything up to ULONG_MAX currently. We can't tell at createblob time how the thing is going to be used, so can't have any kind of property specific limit unfortunately.
The failure I was seeing was for a gamma LUT, so a size limit alone cannot solve the issue.
