In preparation to enabling -Wimplicit-fallthrough, mark switch cases where
we are expecting to fall through.
Notice that, in this particular case, I replaced "Fall thru" with a "Fall
through" annotation and added a dash as a token in order to separate the
"Fall through" annotation from the rest of the comment on the same line,
which is what GCC is expecting to find.

Both fabric_ops.get_fabric_name() and fabric_ops.name are user-facing, with

The same dependency needs to be propagated here to make it work correctly
with CONFIG_THERMAL=m and SCSI_CXGB4_ISCSI=y. That change by itself causes
another problem with a circular dependency, as we use 'select NETDEVICES'.
This is something we really should not do anyway, as a driver symbol should
never select another major subsystem, so let's turn that into a 'depends
on'. I don't see any downsides of that, as NETDEVICES is only disabled in
rather obscure cases that are not relevant to the users of cxgb4i.

"Fall through" in the context of switch case usually means not to have a

old comment meant that here we do not have an _early return_ in the switch

v2.6.30 commit 5ffd51a5e4 ("[SCSI] zfcp: replace current ERP logging with

within zfcp_dbf.*, not within zfcp_erp.c.
This was a bit confusing since the remainder of zfcp does use the term
"trace tag". Also "id" is quite generic and it's not obvious for what.
Just unify it consistently and use the "dbf" prefix to relate the arguments

There is no point for double bookkeeping especially just for tracing. The

traced with zfcp_dbf_hba_fsf_res().
As a side effect, this removes an alignment hole and reduces the size of
struct zfcp_fsf_req, and thus of each pending request, by 8 bytes.

Status read buffers (SRBs, unsolicited notifications) never use a QTCB
[zfcp_fsf_req_create()]. zfcp_fsf_req_send() already uses this to
distinguish SRBs from other FSF request types. We can re-use this method in
zfcp_fsf_req_complete(). Introduce a helper function to make the check for
req->qtcb less magic.
SRBs always are FSF_QTCB_UNSOLICITED_STATUS, so we can hard-code this for
the two trace functions dealing with SRBs.
All other FSF request types have a QTCB and we can get the fsf_command from
there.
zfcp_dbf_hba_fsf_response() and thus zfcp_dbf_hba_fsf_res() are only called
for non-SRB requests so it's safe to dereference the QTCB
[zfcp_fsf_req_complete() returns early on SRB, else calls
zfcp_fsf_protstatus_eval() which calls zfcp_dbf_hba_fsf_response()]. In
zfcp_scsi_forget_cmnd() we guard the QTCB dereference with a preceding NULL
check and rely on boolean shortcut evaluation.
As a side effect, this causes an alignment hole which we can close in
a later patch after having cleaned up all fields of struct zfcp_fsf_req.
