[PATCH] reserve space for swap label
Reserve space in the swap disk header for a LABEL and UUID to be specified.
This has been possible with util-linux-2.12b (via e2fsprogs 1.36
libblkid), and is used by at least FC3 and later. The kernel doesn't
really care about this, but the space shouldn't accidentally be used by
something else either.
Also make the on-disk structures be fixed-size types, instead of "int",
though I don't know of any architecture in use where an "int" isn't the
same size as a "__u32" (all current kernel arches have it as "unsigned
int").
