And is it really supported by kernel? I see in
Documentation/blockdev/zram.txt:
In order to enable compression backend's multi stream support
max_comp_streams must be initially set to desired concurrency
level before ZRAM device initialisation.
I guess that when you set disksize the zram device is "locked" for
setting changes. It means that modify already initialized (created)
zram devices is impossible. You have to reset the device to "unlock"
the device setting.
