Subject: [PATCH 0/2] zsmalloc: small compaction improvements

Hi,
	A tiny series that can reduce the number of
find_alloced_obj() invocations (which perform a linear
scan of sub-page) during compaction. Inspired by Alexey
Romanov's findings.

Sergey Senozhatsky (2):
  zsmalloc: do not scan for allocated objects in empty zspage
  zsmalloc: move migration destination zspage inuse check
