Please read the rest of the thread.

There is no real need for the ".deleted" directory to actually be in the=20
name hierarcy. Thus the presence or absence of a real ".deleted" directory=
=20
won't matter.

In fact, life is easier if the ".deleted" directory isn't in the real=20
hierarcy, as we then don't need to add hooks to isolate it. Adding an=20
inode field to the superblock would let us find the directory.

If we decide we want the directory to be in the namespace, then we will=20
just have to pick a name, and users can't touch that name. The extended=20
attribute stuff is all in ROOT/.attribute so there is precedent for=20
putting these things in the namespace. I'd rather not do that, though, as=
=20
we then have to add hooks to keep users out of the directory.

Take care,

Bill
