From 25eeb667599b192ea850a062d69383ee864c06ab Mon Sep 17 00:00:00 2001 From: Wanpeng Li Date: Wed, 13 Mar 2013 15:06:16 +0800 Subject: zram: fix zram_bvec_read duplicate dump failure message and stat accumulation When zram decompress fails, the code unnecessarily dumps failure messages and does stat accumulation in function zram_decompress_page(), this work is already done in function zram_decompress_page, the patch skips the redundant work.
