Subject: vmscan: print shrink_slab symbol name on negative shrinker objects
X-Git-Tag: v2.6.30-rc1~555
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=88c3bd707c2552bcef93cc3724647903aece159d;p=profile%2Fivi%2Fkernel-adaptation-intel-automotive.git

vmscan: print shrink_slab symbol name on negative shrinker objects

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.
