Hi. This is part of patchset series described in [T]. This is the second take of add-hotplug-support patchset. Changes from the last take[L] are * No ap->hotplug_flags and no atomic bitops helpers. All are handled via dev->dflags and ap->eh_info. Things are much simpler now. * Tighter event handling. Unless a new device is plugged in the middle of reset (there's no generic and reliable way to handle this), no hotplug event is lost. * Stronger SCSI synchronization. There still is a race condition during SCSI scan after hotplugging, but the window is really tiny and there doesn't seem to be a waterproof way to fix it. I don't think the race will ever get triggered and even if it does the worst that can happen is not attaching a SCSI device for a newly detected ATA device. Other than this race condition, everything should be watertight. * Disabled devices are not automatically rescanned on user scan request unless the user explicitly requests scan of the device by specifying the device ID or using wild card. * Probing during driver loading and detaching while unloading are all handled by hotplug. There is only one probing/detaching path now. * Unused ->probe_init, ->probe_reset and all related functions killed.
