When probing the exp-attached sata device, libsas/libata will issue a hard reset in sas_probe_sata() -> ata_sas_async_probe(), then a broadcast event will be received after the disk probe fails, and this commit causes the probe will be re-executed on the disk, and a faulty disk may get into an indefinite loop of probe. Therefore, revert this commit, although it can fix some temporary issues with disk probe failure.

Hence this patch that replaces the create*_workqueue() invocations with the definition of this macro. The WQ_MEM_RECLAIM flag has been retained because I think that flag is necessary for workqueues created by storage drivers.

Cleanup the logic related to generating sense data for PASS-THROUGH commands. Generating sense data for PASS-THROUGH commands would overwrite any eventual (real) sense data received from the device. Honor the D_SENSE bit when generating sense data for PASS-THROUGH commands. (The D_SENSE bit can be set by the user, and determines if the returned sense data should be in fixed format or descriptor format) - ata port allocation cleanups (me) Assign the ata port print_id at port allocation time, such that the ata_port_* print functions can be used earlier in the init call chain. Change the ata port port print_id to use ida_alloc(), such that print_ids will get reused on rmmod + modprobe, instead of being incremented indefinitely. Remove wrappers that only existed in order to export the internal libata functions which they wrapped, and instead export the libata functions directly. - Update SATA_MOBILE_LPM_POLICY Kconfig default to med_power_with_dipm (Mario Limonciello) Using this default was not always a good idea before, because it would break hot plug support. However, with LPM changes in recent kernels, a port marked as external will not enable LPM (in order to not break hot plug), so it is now safe to change the default value of this Kconfig. All major Linux distros have had SATA_MOBILE_LPM_POLICY set to med_power_with_dipm for quite a long time - Convert ahci-fsl-qoriq device tree binding to yaml format (Frank Li) * tag 'ata-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/libata/linux: dt-bindings: ata: ahci-fsl-qoriq: add fsl,ls1046a-ahci and fsl,ls1012a-ahci ata: ahci: Add debug print for external port ata,scsi: Remove wrapper ata_sas_port_alloc() ata: libata-core: Reuse available ata_port print_ids ata: libata: Assign print_id at port allocation time ata: libata-core: Remove local_port_no struct member ata: libata-sata: Remove superfluous assignment in ata_sas_port_alloc() ata: libata-core: Remove support for decreasing the number of ports ata: libata: Remove unused function declaration for ata_scsi_detect() ata,scsi: Remove wrappers ata_sas_tport_{add,delete}() ata: libata-scsi: Check ATA_QCFLAG_RTF_FILLED before using result_tf ata: libata-core: Set ATA_QCFLAG_RTF_FILLED in fill_result_tf() ata: libata-scsi: Do not pass ATA device id to ata_to_sense_error() ata: libata-scsi: Remove redundant sense_buffer memsets ata: libata-scsi: Honor the D_SENSE bit for CK_COND=1 and no error ata: libata-scsi: Do not overwrite valid sense data when CK_COND=1 ata: libata-scsi: Fix offsets for the fixed format sense data dt-bindings: ata: ahci-fsl-qoriq: convert to yaml format ata: Kconfig: Update SATA_MOBILE_LPM_POLICY default to med_power_with_dipm 2024-07-04T09:52:32+00:00 Niklas Cassel cassel@kernel.org 2024-07-03T18:44:25+00:00 urn:sha1:0d3603acffe294ffacaf75b18b46f182b68a50df The ata_sas_port_alloc() wrapper mainly exists in order to export the internal libata function which it wraps. The secondary reason is that it initializes some ata_port struct members. However, ata_sas_port_alloc() is only used in a single location, sas_ata_init(), which already performs some ata_port struct member initialization, so it does not make sense to spread this initialization out over two separate locations. Thus, remove the wrapper and instead export the libata function directly, and move the libsas specific ata_port initialization to sas_ata_init(), which already does some ata_port initialization.
