From: Zhaoyang Huang <zhaoyang.huang@xxxxxxxxxx> Subject: mm: zram: amend SLAB_RECLAIM_ACCOUNT on zspage_cachep 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.
