Subject: mm/zswap: add LRU_STOP to comment about dropping the lru lock
Date: Wed, 27 Nov 2024 13:53:29 +0000
This function has been able to return LRU_STOP since commit b49547ade38a
("mm/zswap: stop lru list shrinking when encounter warm region"). To
reduce confusion, update the comment to also list LRU_STOP as an option.
