Hello,
Currently, SCSI targets doesn't have modalias support. It wasn't an issue
until SCSI device handler came along.
We want the SCSI device handler modules to be insmodded automatically
when the specific SCSI targets are probed and found.
This set of patches adds the modalias support for SCSI targets and
also makes the relevant changes to SCSI device handler modules to
make use of it.
Applies cleanly on 2.6.29-rc8 and is tested on the same.
Please review and consider this for 2.6.30.
Thanks & Regards,

Well, agreed in principle. But do note that ALUA handling really
isn't supported well here.
Problem is that ALUA hooks off a different setting (namely the
'TGPS' bit in the inquiry data) and _not_ on the device name.
In fact, it's well possible to support _both_, old-style
proprietary failover and ALUA.
So to handle this properly we should be adding a 'tgps'
setting to the sysfs data and use this for ALUA keying.
With that we basically can get rid of the device table
in ALUA and live happily ever after.
I'll be posting a patch for this shortly.
We really should be integrating both of them, as
the proposed modalias support is a Good Thing (tm).
Cheers,
Hannes
