So I can't really test it. Also, I replied to the first version of the
patch, there was a better series of four patches.
I tried to look for them on lore, but it looks like linux-scsi isn't
part of the archiving.
The message ID of the 0/4 message is
20190605073942.125577-1-h...@suse.de
All the patches looked sane to me, but I really can't say much else
than "looks good to me" and "it does fix the gcc-9 warning".
Attaching the original emails here for convenience. I "tested" them
(ie applied and built them) on top of plain 5.2, but I don't think
anything has changed anywhere in this area.
Maybe Hannes has more input on this? Maybe even an updated series?

It will only ever be set so another callback, and the pointer to
this callback is available on all locations. So kill it.

Gcc-9 complains for a memset across pointer boundaries, which happens
as the code tries to allocate a flexible array on the stack.
Turns out we cannot do this without relying on gcc-isms, so
with this patch we'll embed the fc_rport_priv structure into
fcoe_rport, can use the normal 'container_of' outcast, and
will only have to do a memset over one structure.

Instead of using the generic 'fc_rport_priv' structure as argument
and then having to painstakingly outcast this to fcoe_rport we should
be passing the fcoe_rport structure itself and reduce complexity.
