The patch titled
ZVC: Support NR_SLAB_RECLAIMABLE / NR_SLAB_UNRECLAIMABLE
has been removed from the -mm tree. Its filename was
zvc-support-nr_slab_reclaimable--nr_slab_unreclaimable-swap_prefetch.patch
This patch was dropped because it was folded into mm-implement-swap-prefetching.patch
------------------------------------------------------
Subject: ZVC: Support NR_SLAB_RECLAIMABLE / NR_SLAB_UNRECLAIMABLE
From: Christoph Lameter <clameter@xxxxxxx>
Remove the atomic counter for slab_reclaim_pages and replace the counter
and NR_SLAB with two ZVC counter that account for unreclaimable and
reclaimable slab pages: NR_SLAB_RECLAIMABLE and NR_SLAB_UNRECLAIMABLE.
Change the check in vmscan.c to refer to to NR_SLAB_RECLAIMABLE. The
intend seems to be to check for slab pages that could be freed.
