How about having a .follow_mount op, and using that instead of default follow_mount in case mounted is incremented? Also I would prefer the patch to add this call keep basically the same API as follow_mount, so if you are going to change that to return an error and do the NOFOLLOW handling in there, then could you do that first, as a more trivial patch? Then your addition of the d_op should not touch outside *follow_mount. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
