Subject: [PATCH] zram: use notify_free to account all free notifications
Date: Fri,  5 Sep 2014 21:57:08 +0900	[thread overview]
Message-ID: <1409921829-12261-1-git-send-email-sergey.senozhatsky@gmail.com> (raw)

Hello,

This patch change the way zram uses `notify_free' stat attr. 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

Please revert 2cbf6f7bea1048ab5 (zram: add num_{discard_req, discarded}
for discard stat) and apply this patch.
