slabinfo: Support printout of the number of fallbacks
Add functionality to slabinfo to print out the number of fallbacks that have occurred for each slab cache when the -D option is specified. Also widen the allocation / free field since the numbers became too big after a week. Signed-off-by: Christoph Lameter <clameter@sgi.com> Signed-off-by: Pekka Enberg <penberg@cs.helsinki.fi>
