From a882dd92de83f7d1634dbde6f1d065d6ac73546e Mon Sep 17 00:00:00 2001 From: Alice Ryhl Date: Wed, 27 Nov 2024 13:53:29 +0000 Subject: [PATCH] mm/zswap: add LRU_STOP to comment about dropping the lru lock 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.
