Greg, Is there some other interrupt-safe alternative: http://lkml.org/lkml/2005/4/29/129 to using device_for_each_child()? The scsi_target_[block/unblock]() functions need to iterate over all the child-scsi_device's belonging to an fc_rport. Thanks, Andrew Vasquez ^ permalink raw reply [flat|nested] 3+ messages in thread

That's what's going into 2.6.13, so you might have some chance there. Otherwise you need to rewrite your logic to not do that :) Good luck, greg k-h ^ permalink raw reply [flat|nested] 3+ messages in thread
