On starting k3b seems to use 'safe for reading' commands and 'safe for writing' command 0x55 (mode_select?) to test the drive function. file->f_mode is returning with 0x0d during 'safe for writing' command.
growisofs also is returning file->f_mode as 0x0d with any 'safe for writing' command if I disable the line and allow k3b to run and burn dvd and just printk the cmd and file->f_mode values ...
I believe FMODE_WRITE is 0x02 tho don't know where that is defined... If this bit not set does it mean the device is opened for reading? during a burn? Sorry, I'm very new to this... but do notice that cdrecord returnes 0x0f which does have the bit set correctly...
