Redis: Free used_memory_rss without restarting redis

Over time the used_memory_rss keeps increasing. I understand the reason behind it getting filled (its how memory allocators work). However I need a solution to free it without restarting redis.

Is there any way to do the same?

in redis 4.0 there is a new command 

MEMORY PURGE

that will defragment memory and release it to the OS.
