Add support for host_tagset. Also move the reserved command slots to the end of the pool to eliminate an addition operation for every SCSI request. This patch was originally authored by Hannes Reinecke here: Link: https://lore.kernel.org/linux-block/20191126131009.71726-8-hare@suse.de/ But we NAKed this patch because we wanted to fully test multipath failover operations.

With clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG), indirect call targets are validated against the expected function pointer prototype to make sure the call target is valid to help mitigate ROP attacks. If they are not identical, there is a failure at run time, which manifests as either a kernel panic or thread getting killed. A proposed warning in clang aims to catch these at compile time, which reveals: drivers/scsi/elx/libefc/efc_node.c:811:22: error: incompatible function pointer types assigning to 'void (*)(struct efc_sm_ctx *, u32, void *)' (aka 'void (*)(struct efc_sm_ctx *, unsigned int, void *)') from 'void (*)(struct efc_sm_ctx *, enum efc_sm_event, void *)' [-Werror,-Wincompatible-function-pointer-types-strict] ctx->current_state = state; ^ ~~~~~ drivers/scsi/elx/libefc/efc_node.c:878:21: error: incompatible function pointer types assigning to 'void (*)(struct efc_sm_ctx *, u32, void *)' (aka 'void (*)(struct efc_sm_ctx *, unsigned int, void *)') from 'void (*)(struct efc_sm_ctx *, enum efc_sm_event, void *)' [-Werror,-Wincompatible-function-pointer-types-strict] node->nodedb_state = state; ^ ~~~~~ drivers/scsi/elx/libefc/efc_node.c:905:6: error: incompatible function pointer types assigning to 'void (*)(struct efc_sm_ctx *, enum efc_sm_event, void *)' from 'void (*)(struct efc_sm_ctx *, u32, void *)' (aka 'void (*)(struct efc_sm_ctx *, unsigned int, void *)') [-Werror,-Wincompatible-function-pointer-types-strict] pf = node->nodedb_state; ^ ~~~~~~~~~~~~~~~~~~ drivers/scsi/elx/libefc/efc_device.c:455:22: error: incompatible function pointer types assigning to 'void (*)(struct efc_sm_ctx *, u32, void *)' (aka 'void (*)(struct efc_sm_ctx *, unsigned int, void *)') from 'void (struct efc_sm_ctx *, enum efc_sm_event, void *)' [-Werror,-Wincompatible-function-pointer-types-strict] node->nodedb_state = __efc_d_init; ^ ~~~~~~~~~~~~ drivers/scsi/elx/libefc/efc_sm.c:41:22: error: incompatible function pointer types assigning to 'void (*)(struct efc_sm_ctx *, u32, void *)' (aka 'void (*)(struct efc_sm_ctx *, unsigned int, void *)') from 'void (*)(struct efc_sm_ctx *, enum efc_sm_event, void *)' [-Werror,-Wincompatible-function-pointer-types-strict] ctx->current_state = state; ^ ~~~~~ The type of the second parameter in the prototypes of ->current_state() and ->nodedb_state() ('u32') does not match the implementations, which have a second parameter type of 'enum efc_sm_event'.

In commit 0b639dec ("scsi: pm8001: Modify task abort handling for SATA task"), code was introduced to dereference "task" pointer in pm8001_abort_task(). However there was a pre-existing later check for "!task", which spooked the kernel test robot. Function pm8001_abort_task() should never be passed NULL for "task" pointer, so remove that check. Also remove the "unlikely" hint, as this is not fastpath code. Reported-by:

The following deadlock has been observed on multiple test setups: * ufshcd_wl_suspend() is waiting for blk_execute_rq(START STOP UNIT) to complete while ufshcd_wl_suspend() holds host_sem. * The SCSI error handler is activated, changes the host state to SHOST_RECOVERY, ufshcd_eh_host_reset_handler() and ufshcd_err_handler() are called and the latter function tries to obtain host_sem. This is a deadlock because blk_execute_rq() can't execute SCSI commands while the host is in the SHOST_RECOVERY state and because the error handler cannot make progress because host_sem is held by another thread. Fix this deadlock as follows: * Fail attempts to suspend the system while the SCSI error handler is in progress by setting the SCMD_FAIL_IF_RECOVERING flag for START STOP UNIT commands. * If the system is suspending and a START STOP UNIT command times out, handle the SCSI command timeout from inside the context of the SCSI timeout handler instead of activating the SCSI error handler. The runtime power management code is not affected by this deadlock since hba->host_sem is not touched by the runtime power management functions in the UFS driver. Reviewed-by:
