Currently, this attr accounts only swap free notifications, iow used only when zram device is a swap device. The patch preserves the existing behaviour and additionally makes `notify_free' universal, so it's also used by zram to account REQ_DISCARDs when zram is not used as a swap device. Please refer to: https://lkml.org/lkml/2014/9/3/1115 V3: -- account all notifications, including those that hit ZRAM_ZERO page V2: -- fix accounting error found by Minchan Kim.
