From 6f560c0f2aa00a3627c748aa0b194b81e99db5d7 Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Tue, 10 Oct 2023 09:34:59 +0800 Subject: [PATCH] f2fs: let f2fs_precache_extents() traverses in file range Rather than in range of [0, max_file_blocks()), since data after EOF is alwasy zero, it's unnecessary to preload mapping info of the data.
