[PATCH 0/2] make automatic device_id generation possible
From: Sergey Senozhatsky
Date: Wed Mar 04 2015 - 09:16:25 EST
Hello,
Make zram-contol/zram_add interface easier to use. Extend it to support
read and write operations.
Write operation remains the same:
echo X > /sys/class/zram-control/zram_add
will add /dev/zramX (or return error).
Read operation is treated as 'pick up available device_id, add new
device and return device_id'.
Example:
cat /sys/class/zram-control/zram_add
2
cat /sys/class/zram-control/zram_add
3
Sergey Senozhatsky (2):
zram: return zram device_id value from zram_add()
zram: introduce automatic device_id generation
