So, was any of this ever implemented? As far as I can tell, the required changes were:
(o) addition of scsi_schedule_host_removal() (possibly optional) (o) implementation of scsi_set_device_offline() (possibly optional) (o) change the behavior of the 'hotplug initialization model' to call my release function Matt On Fri, Jan 24, 2003 at 08:07:29PM -0500, Doug Ledford wrote: > On Fri, Jan 24, 2003 at 04:45:53PM -0800, Matthew Dharm wrote: > > Okay... so what do I do if it fails?
