Subject: vmscan: make drop_slab_node static
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e4b424b7ec8791087375bb1f2480a3ba05d21e0b;p=linux.git

vmscan: make drop_slab_node static

drop_slab_node is only used in drop_slab.  So remove it's declaration
from header file and add keyword static for it's definition.
