The current behavior of the SCSI core is to clear driver-private data before preparing a request for submission to the SCSI LLD. Make it possible for SCSI LLDs to disable clearing of driver-private data. These hooks will be used by a later patch, namely "scsi: ufs: Let the SCSI core allocate per-command UFS data".

Remove cmd_list functionality; no users left. With that the scsi_put_command() becomes empty, so remove that one, too. Link: https://lore.kernel.org/r/20200228075318.91255-14-hare@suse.deReviewed-by:

Use the SCSI midlayer helper to traverse the number of outstanding commands. This also eliminates the last usage for the cmd_list functionality so we can drop it. Link: https://lore.kernel.org/r/20200228075318.91255-13-hare@suse.deReviewed-by:

Instead of traversing the list of possible commands by hands we should be using scsi_host_busy_iter() to figure out if there are outstanding commands. Link: https://lore.kernel.org/r/20200228075318.91255-12-hare@suse.deReviewed-by:

Add an iterator scsi_host_busy_iter() to traverse all busy commands. If locking against concurrent command completions is required, it has to be provided by the caller. Link: https://lore.kernel.org/r/20200228075318.91255-11-hare@suse.deSigned-off-by:

Use scsi_host_block() and scsi_host_unblock() instead of scsi_block_requests()/scsi_unblock_requests() to block and unblock I/O. This has the advantage that the block layer will stop sending I/O to the adapter instead of having the SCSI midlayer requeueing I/O internally.

_aac_reset_adapter() only has one caller, and that one already calls scsi_block_requests(). Move the calls out of _aac_reset_adapter() to avoid calling scsi_block_requests() twice. Link: https://lore.kernel.org/r/20200228075318.91255-8-hare@suse.deReviewed-by:

There is no need to wait for outstanding write commands on synchronize cache; the block layer is responsible for I/O scheduling, no need to out-guess it in the driver layer. Link: https://lore.kernel.org/r/20200228075318.91255-5-hare@suse.deReviewed-by:

Rather than traversing all outstanding commands manually, use the scsi_host_complete_all_commands() helper to terminate all commands during reset. With that we can drop the cmd_list usage from the midlayer. Link: https://lore.kernel.org/r/20200228075318.91255-4-hare@suse.deReviewed-by:

Rename the badly named function into adpt_i2o_scsi_complete(), and make it a void function as the return value is never used. This also fixes a potential use-after-free as the return value might be evaluated from the command result after the command has been freed.

Some delays may be required either after gating or before ungating reference clock for device according to vendor requirements. Note that in UFS 3.0, the delay time after gating reference clock can be defined by attribute bRefClkGatingWaitTime. Use the formal value instead if it can be queried from device.

For N2N, fc_port struct is created during report id acquisition. At later time, the loop resync (fabric, n2n, loop) would trigger the rest of the login using the created fc_port struct. The loop resync logic can trigger another fc_port allocation if the 1st allocation was not able to execute. This patch prevents the 2nd allocation trigger.

commit e4e3a2ce ("scsi: qla2xxx: Add ability to autodetect SFP type") takes a heavy handed approach to BPM (Buffer Plus Management) enablement: 1) During hardware initialization, if an LR-capable transceiver is recognized, the driver schedules a disruptive post-initialization chip-reset (ISP-ABORT) to allow the BPM settings to be sent to the firmware. This chip-reset will result in (short-term) path-loss to all fc-rports and their attached SCSI devices. 2) LR-detection is triggered during any link-up event, resulting in a refresh and potential chip-reset Based on firmware-team guidance, upon LR-capable transceiver recognition, the driver's hardware initialization code will now re-execute firmware with the new BPM settings, then continue on with driver initialization. To address the second issue, the driver performs LR-capable detection upon the driver receiving a transceiver-insertion asynchronous event from firmware. No short-term path loss is needed with this new semantic. Link: https://lore.kernel.org/r/20200226224022.24518-10-hmadhani@marvell.comSigned-off-by:
