We have this code in mm/vmscan.c:shrink_slab() :
...
if (total_scan < 0) {
printk(KERN_ERR "shrink_slab: %pF negative objects to "
"delete nr=%ld\n",
shrinker->shrink, total_scan);
total_scan = max_pass;
}
...
but since 'total_scan' is of type 'unsigned long' it will never be
less than zero, so there is no way we'll ever enter the true branch of
this if statement - so let's just remove it.
