From: Ma Wupeng <mawupeng1@xxxxxxxxxx> The first patch cap zone movable's min wmark to small value since no one can use it. The second patch introduce a per zone watermark to replace the vanilla watermark_scale_factor to bring flexibility to tune each zone's watermark separately and lead to more efficient kswapd. Each patch's detail information can be seen is its own changelog.
