From 277afbde6ca2b38729683fc17c031b4bc942068d Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Thu, 29 Jul 2021 09:22:17 +0800 Subject: [PATCH] f2fs: fix wrong checkpoint_changed value in f2fs_remount() In f2fs_remount(), return value of test_opt() is an unsigned int type variable, however when we compare it to a bool type variable, it cause wrong result, fix it.
