Subject: f2fs: check the generic conditions first
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=e23ab8028de0d92df5921a570f5212c0370db3b5;p=users%2Fjedix%2Flinux-maple.git

f2fs: check the generic conditions first

Let's return errors caught by the generic checks. This fixes generic/494 where
it expects to see EBUSY by setattr_prepare instead of EINVAL by f2fs for active
swapfile.
