We can have multiple zram devices (zram0 .. zramN), I guess it
would make sense not to force all devices to use one particular
allocator (e.g. see comp_algorithm_store()).

If the motivation for the patch set is that zsmalloc does not
perform equally well for various data access patterns, then the
same is true for any other allocator. Thus, I think, we need to
have a per-device 'allocator' knob.
