[ Upstream commit 11e48f5201fd86ffa038809dd9c41144d43ee2e4 ] This loop timeout with "retries" set to -1, not 0. Fix the test for failure.

scsi: mpt3sas: Avoid freeing unallocated PCIe SGL buffers

scsi: qla2xxx: Remove redundant VPD flash read in sysfs read path

2026-09-14T11:20:43+00:00

[ Upstream commit 5cbc49d5c4cd20c18041e86958103045216d2190 ] qla2x00_sysfs_read_vpd() called ha->isp_ops->read_optrom() a second time after releasing optrom_mutex. The repeated read is redundant and, unlike the first, runs without optrom_mutex held, exposing flash access to concurrent optrom operations. Drop the duplicate call.

scsi: smartpqi: Fix AIO retry marker cleared by SCSI core between dispatches.

2026-09-14T11:20:36+00:00

[ Upstream commit 225548863f0a2350c6f34231ca56710c3dd1a5d5 ] On recent Linux kernels the driver can enter a retry loop on the AIO fast path when a request is retried, looping until timeout. A diagnostic path that takes a physical drive offline on AIO-bypass failure is also never entered on affected kernels. Register a per-command initialization callback with the SCSI core. Its presence causes the core to skip the per-dispatch clear, so the retry marker now survives across the requeue and the AIO-to-RAID fallback proceeds as intended. The driver takes over the marker's lifetime: it is zeroed at tag allocation, preserved across the retry requeue so the error path can act on it, and cleared on terminal completion so the tag starts clean on its next use.

scsi: core: Register sysfs attributes earlier

2026-09-14T11:20:36+00:00

[ Upstream commit 92c4b58b15c56298b1b225c1d2e533165b3e32af ] A quote from Documentation/driver-api/driver-model/device.rst: "Word of warning: While the kernel allows device_create_file() and device_remove_file() to be called on a device at any time, userspace has strict expectations on when attributes get created. When a new device is registered in the kernel, a uevent is generated to notify userspace (like udev) that a new device is available. If attributes are added after the device is registered, then userspace won't get notified and userspace will not know about the new attributes." Hence register SCSI host sysfs attributes before the SCSI host shost_dev uevent is emitted instead of after that event has been emitted.
