... except that list_head is not a good match here. For one thing, we never walk that thing backwards. For another, filesystem can be used without ever going through register_filesystem(), making your data structure quite a mess - e.g. use of list_empty() (a perfectly normal list.h primitive) on it might oops on some instances. IOW, what you are making is not quite list_head and pretending it to be list_head is asking for serious headache down the road. Frankly, what's the point? Reusing an existing data type, to avoid DIY is generally a good advice, but then you'd better make sure that existing type *does* fit your needs and that your creation is playing by that type's rules. This patch does neither... NAKed-by: Al Viro <[email protected]>
