The patch titled
Subject: clear_refs: introduce private struct for mm_walk
has been removed from the -mm tree. Its filename was
clear_refs-introduce-private-struct-for-mm_walk.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Pavel Emelyanov <xemul@xxxxxxxxxxxxx>
Subject: clear_refs: introduce private struct for mm_walk
In the next patch the clear-refs-type will be required in
clear_refs_pte_range funciton, so prepare the walk->private to carry this
info.
