scsi: core: Fix the unit attention counter implementation

2025-11-13T20:36:39Z

[ Upstream commit d54c676d4fe0543d1642ab7a68ffdd31e8639a5d ] scsi_decide_disposition() may call scsi_check_sense(). scsi_decide_disposition() calls are not serialized. Hence, counter updates by scsi_check_sense() must be serialized. Hence this patch that makes the counters updated by scsi_check_sense() atomic.

scsi: libsas: Add dev_parent_is_expander() helper

2025-10-15T10:03:43Z

[ Upstream commit e5eb72c92eb724aa14c50c7d92d1a576dd50d7e6 ] Many libsas drivers check if the parent of the device is an expander. Create a helper that the libsas drivers will use in follow up commits.

scsi: libsas: Refactor dev_is_sata()

2025-07-25T13:03:56Z

Use a switch statement in dev_is_sata() to make the code more readable (and probably slightly better than a series of or conditions). Also have this inline function return a boolean instead of an integer. No functional changes.

scsi: scsi_transport_fc: Change to use per-rport devloss_work_q

2025-07-15T00:57:08Z

Configurations with large numbers of FC rports per host instance are taking a very long time to complete all devloss work. Increase potential parallelism by using a per-rport devloss_work_q for dev_loss_work and fast_io_fail_work. Signed-off-by: Ewan D.

scsi: core: Remember if a device is an ATA device

2025-06-16T18:29:59Z

scsi_add_lun() tests the device vendor string of SCSI devices to detect if a SCSI device is in fact an ATA device, in order to correctly handle SATL power management. The function scsi_cdl_enable() also requires knowing if a SCSI device is an ATA device to control the state of the device CDL feature but this function does that by testing for the presence of the VPD page 89h (ATA INFORMATION page). sd_read_write_same() also has a similar test. Simplify these different methods by adding the is_ata field to struct scsi_device to remember that a SCSI device is in fact an ATA one based on the device vendor name test. This field can also allow low level SCSI host adapter drivers to take special actions for ATA devices (e.g. to better handle ATA NCQ errors). With this, simplify scsi_cdl_enable() and sd_read_write_same().

scsi: sd: Remove the stream_status member from scsi_stream_status_header

2025-05-13T02:16:10Z

Having a variable length array at the end of scsi_stream_status_header only causes problems. Remove it and switch sd_is_perm_stream(), which is the only place that currently uses it, to use the scsi_stream_status directly following it in the local buf structure. Besides being a much better data structure design, this also avoids a -Wflex-array-member-not-at-end warning. Reported-by: Gustavo A. R.
