Subject: [PATCHv3 0/4] zsmalloc: make zspage chain size configurable
Hi,
This turns hard coded limit on maximum number of physical
pages per-zspage into a config option. It also increases the default
limit from 4 to 8.
v3:
-- Fixed zspage isolated bitfield overflow (Mike)
-- Fixed parisc64 build failure (0day)
-- Minumum chain size value is 4 now (which has been zsmalloc default
for ages)
-- Picked up Minchan's Acked-by
Sergey Senozhatsky (4):
zsmalloc: rework zspage chain size selection
zsmalloc: skip chain size calculation for pow_of_2 classes
zsmalloc: make zspage chain size configurable
zsmalloc: set default zspage chain size to 8
