[dm-devel] [PATCH 0/5] Update scsi_dh infrastructure

[Hannes Reinecke]

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
