Use fc_block_rport() instead of fc_block_scsi_eh() as the SCSI command
will be removed as argument for SCSI EH functions.

Instead of passing the a function we can as well return a status
and call the function directly afterwards.

mptscsih_dev_reset() is _not_ a device reset, but rather a
target reset. Nevertheless it's being used for either purpose.
This patch adds a correct implementation for mptscsih_dev_reset(),
and renames the original function to mptscsih_target_reset().
And modifies mptsas and mptspi to call mptscsih_target_reset().

When calling bus_reset we have potentially several ports to be
reset, so this patch open-codes the existing mptfc_block_error_handler()
to wait for all ports attached to this bus.

When sending a TMF we're only concerned with the rport and the LUN ID,
so use struct fc_rport as argument for qedf_initiate_tmf().

Why replace the fc_block helper here in the abort handler?
Isn't the scope of the abort hander exactly the one scsi_cmnd?
The description of this patch is about changes to TMF (so I understand the
change in qedf_initiate_tmf() above for device or target reset), i.e. not abort.
Admittedly, it shouldn't be a problem functional-wise, as fc_block_scsi_eh()
delegates internally to fc_block_rport(), but it looks odd to me nonetheless.
This change seems inconsistent with the other patches in this series.
You don't plan to get rid of fc_block_scsi_eh(), do you?
Oh, later in patch 09 you write:
"Use fc_block_rport() instead of fc_block_scsi_eh() as the latter
will be deprecated."
Why?
Then all FCP HBA abort handlers need to convert their scsi_cmnd to fc_rport
themselves.
E.g. zfcp_scsi_eh_abort_handler() does not deal with fc_rport so far as there
was no need. From what I've seen you haven't touched that part in
[PATCH v2 03/24] zfcp: open-code fc_block_scsi_eh() for host reset
when zfcp was still part of the series, so I smell an inconsistency.
Haven't seen that coming. Did I miss this having been announced explicitly
somewhere else earlier? If not, I would find it interesting to being made
explicit. In retrospectice, I found some hints hidden in individual patches of
earlier version in this series, but I had completely missed it.
Also, it seems a separate topic, not necessarily related to changing the
scsi_eh callback API for dev/target/bus/host reset to get rid of their
unsuitable argument scsi_cmnd.

Yeah, sorry, that is misleading. I had an earlier patchset where I tried
to phase it out, only to find out that this is not the best of ideas.
So no worries, everything will stay as-is in that area.
Will be modifying the patch (and the description) for the next round.
Cheers,
Hannes

When a LUN or target reset is issued we should not rely on a scsi
command to be present; we'll have to reset the entire device or
target anyway.

For target reset we need a device to send the target reset to,
so open-code the loop in target reset to send the target reset TMF
to the correct device.

The code for aborting an outstanding command is a copy of the
functionality from command abort. As we already have called this
function once we reach host reset there's no point in trying to
do so again.

When calling a host reset we shouldn't rely on the command triggering
the reset, so allow megaraid_abort_and_reset() to be called with a
NULL scb.
And drop the pointless 'bus_reset' and 'target_reset' handlers, which
just call the same function as host_reset.
