Are there any views on this patch? I would have thought that the parties
who use the drivers based on libsas would be interested in fixing this bug.


I should have added the before and after logs earlier, so the issue is illustrated. Now attached. When a 24-port expander is unplugged we get >6k lines of WARN on the console, lasting >30 seconds. Not nice.

 BTW, We are internally testing, hence the RFC.

Thanks in advance,

A sample WARN is as follows:

(this can be really huge when an expander is unplugged)

The problem is with the process of sas_port and domain_device
destruction in domain revalidation. There is a 2-stage process:
In domain revalidation (which runs in work queue context), if a
domain_device is discovered to be gone, then the following happens:
- the domain_device is queued for destruction in a separate work item
- the associated sas_port is destroyed immediately

This causes a problem in that the sas_port associated with
a domain_device is destroyed prior the domain_device: this causes
the sysfs WARN. Essentially the "rug has been pulled from underneath".

Also, likewise, when a root port is deformed due to loss of signal,
we have the same issue.

To solve, destroy the sas_port in a separate work item to which
we do the domain revalidation with a new discovery event, as follows:
- When a domain_device is detected to be gone, the domain_device is
  queued for destruction in a separate work item. The associated
  sas_port is also queued for destruction in another separate work item
  (needs to be queued 2nd)
- the domain_device is destroyed
- the sas_port is destroyed
[similar is done for loss of signal event, in sas_port_deformed()].

rediscovery competing with ata error handling
