[PATCH] mm: zram: amend SLAB_RECLAIM_ACCOUNT on zspage_cachep

[Huangzhaoyang]

From: Zhaoyang Huang <zhaoyang.huang@xxxxxxxxxx>

Zspage_cachep is found be merged with other kmem cache during test, which
is not good for debug things(zs_pool->zspage_cachep present to be another
kmem cache in memory dumpfile). It is also neccessary to do so as shrinker has
been registered for zspage. Amending this flag can help kernel to calculate
SLAB_RECLAIMBLE correctly.
