James, Martin,
this is the zfcp patch set for the v4.18 merge window.
The patches apply to Martin's 4.18/scsi-queue.
The patches eventually go on top of the bug fix commit
fa89adba1941e4f3b213399b81732a5c12fd9131
("scsi: zfcp: fix infinite iteration on ERP ready list")
in Martin's 4.17/scsi-fixes or James' scsi-fixes
[https://www.spinics.net/lists/linux-scsi/msg120124.html].
There should be no merge conflicts between the fix and this patch set.
Patches 1-7 are debugging/tracing fixes found during function test of 8-14.
Patches 8-14 are the result of an earlier RFC to prepare for changing
scsi_eh callback function arguments to decouple from scsi_cmnd.

https://marc.info/?l=linux-scsi&m=150099208822680&w=2]
The only difference is that I have to defer the conversion of host_reset().
Patches 15-25 are small cleanups / updates.
