We are already planning to radically change the interface to be more flexible and, above all to make the ntfs->posix translation a module so that it can be replaced for richer or different then posix file systems. > I propose something of the form > > int > vfs_ioctl( struct connection_struct * conn, struct files_struct * fsp, > ...); > > or something like > > int > vfs_ioctl ( struct connection_struct * conn, struct files_struct * fsp, > ulong cmd, void * inbuf,size_t in_size, void* outbuf, size_t out_size). > of course I realize the nightmare of maintaining an IOCTL list, but I am > hoping in the case of SAMBA it would not be as bad as something like an > OS, and this feature will be used to add extensions to SAMBA so that > the capabilities of underlying file systems can be reflected more > accurately in SAMBA. I'm not sure this is a good idea. How would you like to use these ioctl then? Simo. -- Simo Sorce - [EMAIL PROTECTED] Xsec s.r.l. via Durando 10 Ed.
