Update scsi_dh infrastructure
cover Update scsi_dh infrastructure
Hi all,
this patchset updates the scsi_dh infrastructure as posted by Chandra Seetharman recently.
Main changes are to switch to a single notifier callback instead of a per-handler one and adding a sysfs attribute which allow to control the device handler manually. Quite useful for testing.
I've converted all handlers for the new infrastructure; in addition I've updated all handlers (except RDAC, Hi Chandra!) to refuse to attach to a device which does _not_ support the appropriate method.
Except hp_sw, that is, as I didn't found a way of reliably detect this.
And I've added a generic SPC-3 ALUA handler.
Cheers,
Hannes
