move mount_capable() calls to vfs_get_tree() sget_fc() is called only from ->get_tree() instances and the only instance not calling it is legacy_get_tree(), which calls mount_capable() directly. In all sget_fc() callers the checks could be moved to the very beginning of ->get_tree() - ->user_ns is not changed in between. So lifting the checks to the only caller of ->get_tree() is OK.
