[PATCH 5.14 089/432] f2fs: fix wrong checkpoint_changed value in f2fs_remount()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Chao Yu <chao@xxxxxxxxxx>

[ Upstream commit 277afbde6ca2b38729683fc17c031b4bc942068d ]

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.

Fixes: 4354994f097d ("f2fs: checkpoint disabling")
