This doesn't compile on linux-next:

mm/vmscan.c: In function ‘shrink_slab_node’:
mm/vmscan.c:300:23: error: ‘max_pass’ undeclared (first use in this function)
mm/vmscan.c:300:23: note: each undeclared identifier is reported only once for each function it appears in

because of b01fa2357bca ("mm: vmscan: shrink all slab objects if tight on 
memory") from an author with a name remarkably similar to yours.  Could 
you rebase this series on top of your previous work that is already in 
-mm?
