I meant there was a discussion that in the linux mainline kernel there should not be a filesystem which has files that can have files. A file as directory was introduced to unifiy namespace by namesys. > Subfiles mean one more step in the procedure of name resolution. > You should return an allocated inode to vfs for every such subfile. > So subfiles also can not be hidden.

I know you stress this quiet often in your mails. Or is it just your focussing for now to get reiser4 mainline? Is it not possible to introduce new extended features in reiser4 and hide these features vfs? In reiser4 there is no such possibility to introduce a new kind of file which is hidden from vfs? Semantics of reiser5 are totally out of scope here, but I thought of them as implementable above/on reiser4 - reiser4 as the technical grounds for reiser5 (as announced by namesys).
