It takes pages that are 12 significant performance improvement if reads from the compressed cache are 26 Zswap evicts pages from compressed cache on an LRU basis to the backing swap 27 device when the compressed pool reaches its size limit. This requirement had 42 back into memory all of the pages stored in the compressed pool. The 43 pages stored in zswap will remain in the compressed pool until they are 45 pages out of the compressed pool, a swapoff on the swap device(s) will 47 compressed pool. 53 evict pages from its own compressed pool on an LRU basis and write them back to 54 the backing swap device in the case that the compressed pool is full.
