I'm missed at least that part :-) Oh and finally, one last question for today ... In drivers/ide, we have a call to ledtrig_ide_activity() inside ide_do_rw_disk() which allows me to flash the front light on the powerbook. libata has no such thing. It's as simple as adding that call, if we want to keep the trigger named "ide-disk" but where to put it then ? In ata_scsi_rw_xlat() ? Yuck :-) Another option is to stick it in drivers/scsi/sd.c but the trigger should not be named ide-disk anymore ... Also it will start tiggering for any "pseudo scsi" device in the machine which is note quite the purpose... It would be nice if it really only triggered on libata and as such blink the led only for the internal HD on those powerbooks (unless you have some libata based PCMCIA stuff but that doesn't matter). Anyway, nothing fancy, just a quick hack to get the activity led back :-) I could always stick it somewhere in pata_macio.c but that would suck probably even more.
