The same out of tree filesystems depend on ->get_sb() being there...
See Documentation/filesystems/porting:

[mandatory]
        ->get_sb() is gone.  Switch to use of ->mount().  Typically it's just
a matter of switching from calling get_sb_... to mount_... and changing the
function type.  If you were doing it manually, just switch from setting ->mnt_root
to some pointer to returning that pointer.  On errors return ERR_PTR(...).

IOW, odds are good that you'll need to do something like what had been
done in commit 152a08366671080f27b32e0c411ad620c5f88b57 - not terribly
complicated.
