From: Sergey Senozhatsky
Date: Fri Jun 23 2023 - 00:40:36 EST


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
