The patch titled
Subject: mm/zswap.c: change params from hidden to ro
has been removed from the -mm tree. Its filename was
mm-zswapc-change-params-from-hidden-to-ro.patch

------------------------------------------------------
From: Dan Streetman <ddstreet@xxxxxxxx>
Subject: mm/zswap.c: change params from hidden to ro
The "compressor" and "enabled" params are currently hidden, this changes
them to read-only, so userspace can tell if zswap is enabled or not and
see what compressor is in use.
