Subject: [PATCH -next 0/2] watermark related improvement on zone movable

From: Ma Wupeng <mawupeng1@...wei.com>

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.
