From bd409934c0619a6c3507891844aeb0c0dca69e18 Mon Sep 17 00:00:00 2001 From: Zhiguo Niu Date: Mon, 10 Feb 2025 09:24:09 +0800 Subject: [PATCH] f2fs: fix to return SHRINK_EMPTY if no objects to free Quoted from include/linux/shrinker.h "count_objects should return the number of freeable items in the cache. If there are no objects to free, it should return SHRINK_EMPTY, while 0 is returned in cases of the number of freeable items cannot be determined or shrinker should skip this cache for this time (e.g., their number is below shrinkable limit)."
