Subject: vmscan: print shrink_slab symbol name on negative shrinker objects
From: David Rientjes <rientjes@xxxxxxxxxx>
When a shrinker has a negative number of objects to delete, the symbol
name of the shrinker should be printed, not shrink_slab. This also makes
the error message slightly more informative.
