Re: [DMAPI] code error in dm_ip_to_handle()

[Aurelien Degremont - Stagiaire <degremont@xxxxxxxxxxx>]

To sum up :
 - inode_to_fh() only need to fill a dmfsfid (currently :)) with 
something like that :
        fid.dm_fid_len = sizeof(dm_fid_t) - sizeof(fid.dm_fid_len);
        fid.dm_fid_pad = 0;
        fid.dm_fid_gen = ip->i_generation;
        fid.dm_fid_ino = ip->i_ino;
        memcpy(dmfsfid, &fid, sizeof(fid));

(The dm_fid_len don't need to be set to 0)

 - fh_to_inode() must test the fid_len field and return the root inode 
number if its value is zero.
        dm_fid_t fid;

        /* FS HANDLE */
        if (dmfsfid->fid_len == 0)
                ino = EXT3_ROOT_INO;
        /* FILE HANDLE */
        else
        {
                memcpy(&fid, dmfsfid, sizeof(fid));
                ino = fid.dm_fid_ino; /* Some alignement checks ? */
        }

The other modification are managed by the DMAPI code and the FS code 
don't need to bother with it ?
