invoking zcache w/o using a workload

Thanks Mulyadi for your response.

zcache has cleancache (a third level page cache) and front swap(swap
cache). I am trying to trigger clean cache and now the swap device.
But my guess is reducing the memory should also cause these evictions
rapidly.

Thanks,
Asim

Is there a way I can trigger zcache_get/put (specifically clean cache)
with a simple unit test (as opposed to running a workload) ? This will
greatly reduce my test/build time.

I am a new user of zcache (due to playing with recent Mint release).

I got impression that by reducing mapped memory you have (using "mem="
kernel parameter) and putting zram/zcache into high priority swap, is
enough to quickly trigger allocation into zcache. of course, you need
memory hogger for that, something like "tail -f /dev/zero".

CMIIW if misunderstood you...
