I have posted the same fix several times, e.g.

Hi,
I would like to ask for advice, prior to submitting a patch for our lldd
zfcp, or alternatively for common code.
Someone reported this warning and function call stack:

Steffen Maier has pointed me at:

It is important to kick the erp thread only for actions in the running list,
though, as an imbalance of wakeup signals would confuse the erp thread
otherwise.

I am afraid this patch can't be applied as it is.
The problem is that the code doesn't take into account that older adapters do
not provide the data which your patch tries to extract. There is a feature flag
for that in the hardware specification. So the right response to Heiko's

to

This would allow to specify the order of hosts within the scope of a
single HBA driver. Currently it depends on the order of detection and
registration of HBAs at module or kernel initialization. But, what is
about hosts being unavailable at this time sometimes and becoming
operational later? If HBA drivers would pass an unique identifier for each
detected host (let's assume unique_id) additionally to scsi_register, then
the mid layer could match this against identifiers known from the
scsihosts parameter and put the host into the predefined position.
