Subject: [PATCHv2 0/7] introduce dynamic device creation/removal
Date: Sun,  1 Mar 2015 17:42:36 +0900	[thread overview]
Message-ID: <1425199363-15590-1-git-send-email-sergey.senozhatsky@gmail.com> (raw)

Hello,

This patchset introduces zram-control sysfs class, which has two sysfs
attrs:
 - zram_add	-- add a new specific (device_id) zram device
 - zram_remove	-- remove a specific (device_id) zram device


    Usage example:
        # add a new specific zram device
        echo 4 > /sys/class/zram-control/zram_add

        # remove a specific zram device
        echo 4 > /sys/class/zram-control/zram_remove


Patch set also does some cleanups and huge code reorganization.

v2:
switch to sysfs class, rather than using /dev/zram-control node and
doing IOCTL on it. we lose some features, though. like automatic
device_id generation.

Sergey Senozhatsky (7):
  zram: cosmetic ZRAM_ATTR_RO code formatting tweak
  zram: use idr instead of `zram_devices' array
  zram: factor out device reset from reset_store()
  zram: reorganize code layout
  zram: add dynamic device add/remove functionality
  zram: remove max_num_devices limitation
  zram: report every added and removed device
