[f2fs-dev] [PATCH] f2fs: check return value of freeze_super()

[Chao Yu]

freeze_super() can fail, it needs to check its return value and do
error handling in f2fs_resize_fs().

Fixes: 04f0b2eaa3b3 ("f2fs: ioctl for removing a range from F2FS")
Fixes: b4b10061ef98 ("f2fs: refactor resize_fs to avoid meta updates in progress")
