Sparse issues an "symbol 'saved_parents_slab' was not declared. Should
it be static?" warning. In order to suppress the warning, since this
symbol does not require more than file visibility, we simply add the
static modifier to its declaration.

Hi Thomas,

In addition to the gcc warning, sparse weighs in with this warning,
provoked by commit 3b3d83e5 ("[PERHAPS LIKE THIS] log: use true parents
for diff even when rewriting", 22-07-2013).

If you update this commit, could you please squash this into the new patch.

Thanks!

ATB,
Ramsay Jones
