Subject: Re: [RFC 6/9] scsi: fc: start decoupling fc_block_scsi_eh from scsi_cmnd

Steffen,
> Scsi_cmnd is an unsuitable argument for eh_device_reset_handler(),
> eh_target_reset_handler(), and eh_host_reset_handler() which do not
> have the scope of one single SCSI command. These callbacks tend to
> use fc_block_scsi_eh() requiring scsi_cmnd. In order to start
> decoupling above eh callbacks from scsi_cmnd, introduce a new variant
> of the function called fc_block_rport() taking an fc_rport as
> argument. Refactor the old fc_block_scsi_eh() to simply delegate to
> fc_block_rport().
Applied to 4.14/scsi-queue. Thanks!
