Can Any one give me some design documents of samba.

That will work fine, and avoid a database lookup, but will make it OS and
file system dependent. My patch will work on any architecture and file
system that samba can use (and the price of tdb lookups).

The problem isn't with keeping both sets of permissions, but rather keeping
them to mean the same semantics (as much as that's possible). This is needed
so people coming in over NFS don't have a completely disjoint set of
permissions than people coming in over CIFS. In your case this work should
be done in the kernel.

ioctl's? Watch for performance hits there.

I think the code is the closest thing your gonna get :-)
