[PATCH 0/2] qcow2: Limit total allocation range to INT_MAX

[Max Reitz]

Hi,

While looking for why handle_alloc_space() seems to cause issues on
ppc64le+XFS (performance degradation and data corruption), I spotted
this other issue.  It isn’t as bad, but still needs fixing.

See patch 1 for what is fixed and patch 2 for what breaks otherwise.
