The acornscsi driver has a config option to enable tagged queuing, but this option gets disabled in the driver itself with the comment 'needs to be debugged'. As this is a _really_ old driver I doubt anyone will be wanting to invest time here, so remove the tagged queue vestiges and make our lives easier.

This reverts commit a113eaaf. There are a couple of issues with the commit: 1. It causes deadlocks. 2. It causes the shost->eh_cmd_q list of failed requests not to be processed, ever. So revert it. 1. Deadlocks The SCSI error handler runs with requests blocked beginning when scsi_schedule_eh() sets SHOST_RECOVERY state, continuing through scsi_error_handler() callback ->eh_strategy_handler() until scsi_restart_operations() is called. By setting eh_strategy_handler to ufshcd_err_handler, the patch changed the UFS error handler to run with requests blocked, including PM requests, for the entire run of the error handler. That conflicts with UFS error handler existing synchronization with UFS device PM operations. The UFS error handler synchronizes with runtime PM by doing pm_runtime_get_sync() prior to blocking requests itself. It synchronizes with system PM by use of hba->host_sem, again before blocking requests itself. However, if requests are already blocked, then PM operations will block. So: the UFS error handler blocks waiting on PM + PM blocks waiting on SCSI PM requests to process or fail + PM requests are blocked waiting on error handling to finish = deadlock This happens both for runtime PM and system PM. Prior to the patch, these deadlocks could not happen even if SCSI error handling was running, because the presence of requests in shost->eh_cmd_q would mean the queues could not be suspended, which would mean that, should the UFS error handler run at the same time, it would not need to wait for PM or vice versa. Please note these scenarios are not just theoretical, they were found during testing on a Samsung Galaxy Book S. 2. ->eh_strategy_handler() must process shost->eh_cmd_q list of failed requests, as all other eh_strategy_handler's do except UFS error handler. Refer for example: scsi_unjam_host(), ata_scsi_error() and sas_scsi_recover_host().

device_initialize() is used to take a refcount on the device. However, put_device() is not called during device teardown. This leads to a leak of private data of the driver core, dev_name(), etc. This is reported by kmemleak at boot time if we compile kernel with DEBUG_TEST_DRIVER_REMOVE. Fix memory leaks during unregistration and implement a release function.

Commit 356ba2a8 ("scsi: target: tcmu: Make pgr_support and alua_support attributes writable") introduced support for changeable alua_support and pgr_support target attributes. These can only be changed if the backstore is user-backed, otherwise the kernel returns -EINVAL. This triggers a warning in the targetcli/rtslib code when performing a target restore that includes non-userbacked backstores: # targetctl restore Storage Object block/storage1: Cannot set attribute alua_support: [Errno 22] Invalid argument, skipped Storage Object block/storage1: Cannot set attribute pgr_support: [Errno 22] Invalid argument, skipped Fix this warning by returning an error code only if we are really going to flip the PGR/ALUA bit in the transport_flags field, otherwise we will do nothing and return success. Return ENOSYS instead of EINVAL if the pgr/alua attributes can not be changed, this way it will be possible for userspace to understand if the operation failed because an invalid value has been passed to strtobool() or because the attributes are fixed.

Reporting zones on a SCSI device sometimes fail with the following error: [76248.516390] ata16.00: invalid transfer count 131328 [76248.523618] sd 15:0:0:0: [sda] REPORT ZONES start lba 536870912 failed The error (from drivers/ata/libata-scsi.c:ata_scsi_zbc_in_xlat()) indicates that buffer size is not aligned to SECTOR_SIZE. This happens when the __vmalloc() failed. Consider we are reporting 4096 zones, then we will have "bufsize = roundup((4096 + 1) * 64, SECTOR_SIZE)" = (513 * 512) = 262656. Then, __vmalloc() failure halves the bufsize to 131328, which is no longer aligned to SECTOR_SIZE. Use rounddown() to ensure the size is always aligned to SECTOR_SIZE and fix the comment as well.

But a review of other elements and warnings were also evaluated. This patch corrected several items in the original patch: - Using be32_to_cpu() on a be16 data type - cpu_to_le32() used on a std uint32_t (CPU) data type. Note: This is a byte array, but stored in LE layout by hardware at 32-bit boundaries. So it possibly needed conversion. - Using cpu_to_le32() on a std uint16_t and assigned to a char typeA - Using le32_to_cpu() on a le16 type - Missing cpu_to_le16() on an assignment Link: https://lore.kernel.org/r/20210830231243.6227-1-jsmart2021@gmail.com Fixes: 9064aeb2 ("scsi: lpfc: Add EDC ELS support") Reported-by:

Most of the arguments are pointers to data structures. But for the EFC_EVT_NPORT_TOPOLOGY_NOTIFY event, the argument is an enum value, and the code is typecasting the void * to an enum generating the warning. Fix by converting the EFC_EVT_NPORT_TOPOLOGY_NOTIFY event to pass a pointer to the enum, thus it's a straight-forward pointer dereference in the event handler.

Pull CPU hotplug updates from Thomas Gleixner: "Updates for the SMP and CPU hotplug: - Remove DEFINE_SMP_CALL_CACHE_FUNCTION() which is a left over of the original hotplug code and now causing trouble with the ARM64 cache topology setup due to the pointless SMP function call. It's not longer required as the hotplug callbacks are guaranteed to be invoked on the upcoming CPU. - Remove the deprecated and now unused CPU hotplug functions - Rewrite the CPU hotplug API documentation" * tag 'smp-urgent-2021-09-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: Documentation: core-api/cpuhotplug: Rewrite the API section cpu/hotplug: Remove deprecated CPU-hotplug functions. thermal: Replace deprecated CPU-hotplug functions. drivers: base: cacheinfo: Get rid of DEFINE_SMP_CALL_CACHE_FUNCTION() -

Merge tag 'char-misc-5.15-rc1-lkdtm' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc Pull misc driver fix from Greg KH: "Here is a single patch for 5.15-rc1, for the lkdtm misc driver. It resolves a build issue that many people were hitting with your current tree, and Kees and others felt would be good to get merged before -rc1 comes out, to prevent them from having to constantly hit it as many development trees restart on -rc1, not older -rc releases. It has NOT been in linux-next, but has passed 0-day testing and looks 'obviously correct' when reviewing it locally :)" * tag 'char-misc-5.15-rc1-lkdtm' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: lkdtm: Use init_uts_ns.name instead of macros
