The patch titled
uml: make 64-bit COW files compatible with 32-bit ones
has been removed from the -mm tree. Its filename is
uml-make-64-bit-cow-files-compatible-with-32-bit-ones.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.
From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@xxxxxxxx>
This is the minimal fix to make 64-bit UML binaries create 32-bit compatible
COW files and read them. I've indeed tested that current code doesn't do this
- the code gets SIGFPE for a division by a value read at the wrong place,
where 0 is found.
