IDE device unplug TODO :) * add ide_device_get() helper which will check for drive->present + increase reference count on drive->gendev and ide_device_put() helper which will decrease reference count on drive->gendev * propagate usage of these helpers to device drivers (ide_disk_get() etc.) so there won't be _new_ requests after removal of the device * if !drive->present fail _old_ requests (as already mentioned by Jens) * add proper locking around drive->present * ... first three points should be relatively easy Bartlomiej - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
