But it has the problem that new and out-of-tree filesystems might forget to do it. Which is why I suggest adding a kmem_cache* argument to unregister_filesystem() for this. It's a bit awkward, and the fs can pass in NULL if it knows what it's doing. But it's reliable. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
