Subject: Re: [EXT] Re: [PATCH v3 1/1] tracing: Fix compile error in trace_array
 calls when TRACING is disabled

Since Steve is travelling, trying Ingo, who is a co-maintainer of trace 
stuff.

Hi Ingo,

If you could review/approve the patch, that would be very helpful, as this 
is a build breaker fix.

Please see the link below for more context:

Most recent (v3) patch posting:
https://lore.kernel.org/linux-scsi/20220907233308.4153-2-aeasi@marvell.com/

Steve suggesting to take the patch via SCSI tree:

Regards,
-Arun
