Docs/subsystem-apis: Remove '[The ]Linux' prefixes from titles of listed documents

2023-01-24T22:27:08Z

Some documents that listed on subsystem-apis have 'Linux' or 'The Linux' title prefixes. It's duplicated information, and makes finding the document of interest with human eyes not easy. Remove the prefixes from the titles.

scsi: core: Change the return type of .eh_timed_out()

2022-10-22T03:25:59Z

Commit 6600593cbd93 ("block: rename BLK_EH_NOT_HANDLED to BLK_EH_DONE") made it impossible for .eh_timed_out() implementations to call scsi_done() without causing a crash. Restore support for SCSI timeout handlers to call scsi_done() as follows: * Change all .eh_timed_out() handlers as follows: - Change the return type into enum scsi_timeout_action. - Change BLK_EH_RESET_TIMER into SCSI_EH_RESET_TIMER. - Change BLK_EH_DONE into SCSI_EH_NOT_HANDLED. * In scsi_timeout(), convert the SCSI_EH_* values into BLK_EH_* values.

scsi: ufs: core: Read device property for ref clock

2022-07-19T03:04:12Z

UFS storage devices require bRefClkFreq attribute to be set to operate correctly at high speed mode. The necessary value is determined by what the SoC / board supports. The standard doesn't specify a method to query the value, so the information needs to be fed in separately. DT information feeds into setting up the clock framework, so platforms using DT can get the UFS reference clock frequency from the clock framework. A special node "ref_clk" from the clock array for the UFS controller node is used as the source for the information. On the platforms that do not use DT (e.g. Intel), the alternative mechanism to feed the intended reference clock frequency is necessary. Specifying the necessary information in DSD of the UFS controller ACPI node is an alternative mechanism proposed in this patch. Those can be accessed via firmware property facility in the kernel and in many ways simillar to querying properties defined in DT. This patch introduces a small helper function to query a predetermined ACPI supplied property of the UFS controller, and uses it to attempt retrieving reference clock value, unless that was already done by the clock infrastructure.

scsi: core: Remove reserved request time-out handling

2022-07-06T12:33:53Z

The SCSI core code does not currently support reserved commands. As such, requests which time-out would never be reserved, and scsi_timeout() 'reserved' arg should never be set. Remove handling for reserved requests, drop the wrapper scsi_timeout() as it now just calls scsi_times_out() always, and finally rename scsi_times_out() -> scsi_timeout() to match the blk_mq_ops method name.
