Subject: f2fs: check return value of freeze_super()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=8bec7dd1b3f7d7769d433d67bde404de948a2d95;p=linux.git

f2fs: check return value of freeze_super()

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")
