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:

Since the SCSI core does not reuse the tag of the SCSI command that is being aborted by .eh_abort() before .eh_abort() has finished it is not necessary to check from inside that callback whether or not the SCSI command has already completed. Instead, rely on the firmware to return an error code when attempting to abort a command that has already completed. Additionally, rely on the firmware to return an error code when attempting to abort an already aborted command. In qla2x00_abort_srb(), use blk_mq_request_started() instead of sp->completed and sp->aborted.

When replacing the Big Kernel Lock in commit 2a48fc0a ("block: autoconvert trivial BKL users to private mutex"), the lock was replaced with a sr-wide lock. This causes very poor performance when using multiple sr devices, as the sr driver was not able to execute more than one command to one drive at any given time, even when there were many CD drives available. Replace the global mutex with per-sr-device mutex. Someone tried this patch at the time, but it never made it upstream, due to possible concerns with race conditions, but it's not clear the patch actually caused those: https://www.spinics.net/lists/linux-scsi/msg63706.html https://www.spinics.net/lists/linux-scsi/msg63750.html Also see http://lists.xiph.org/pipermail/paranoia/2019-December/001647.html Link: https://lore.kernel.org/r/20200218143918.30267-1-merlijn@archive.orgAcked-by:

This kernel configuration is basically enabling/disabling sr driver quirks detection. While these quirks are for fairly rare devices (very old CD burners, and a glucometer), the additional detection of these models is a very minimal amount of code. The logic behind the quirks is always built into the sr driver. This also removes the config from all the defconfig files that are enabling this already.

The 'ch' device node is created before the configuration is being read in, which leads to a race window when ch_open() is called before that. To avoid any races we should be taking the device mutex during ch_readconfig() and ch_init_elem(), and also during ch_open(). That ensures ch_probe is finished before ch_open() completes.

The SCSI device is required to be present during ch_probe() and ch_open(). But the SCSI device itself is only checked during ch_open(), so it's anyones guess if it had been present during ch_probe(). And consequently we can't reliably detach it during ch_release(), as ch_remove() might have been called first. So initialize the changer device during ch_probe(), and take a reference to the SCSI device during both ch_probe() and ch_open().
