Now with percpu refcounting for se_lun in place, go ahead and drop the legacy per se_cmd accounting for se_lun shutdown. This includes __transport_clear_lun_from_sessions(), the associated transport_lun_wait_for_tasks() logic, along with a handful of now unused se_cmd structure members and ->transport_state bits.

This patch adds percpu refcounting for se_lun access that allows the association of an se_lun + se_cmd in transport_lookup_cmd_lun() to occur without an extra list_head for tracking outstanding I/O during se_lun shutdown. This effectively changes se_lun shutdown logic to wait for outstanding I/O percpu references to complete in transport_lun_remove_cmd() using se_lun->lun_ref_comp, instead of explicitly draining the per se_lun command list and waiting for individual se_cmd descriptor processing to complete.

This patch changes iscsit_check_dataout_hdr() to no longer generate REJECTs for zero-length DataOUTs, and instead simply ignore these requests. This follows RFC-3720, Section 10.7.7. DataSegmentLength "This is the data payload length of a SCSI Data-In or SCSI Data-Out PDU. The sending of 0 length data segments should be avoided, but initiators and targets MUST be able to properly receive 0 length data segments."

This patch adds support for completion interrupt coalescing that allows only every ISERT_COMP_BATCH_COUNT (8) to set IB_SEND_SIGNALED, thus avoiding completion interrupts for every posted iser_tx_desc. The batch processing is done using a per isert_conn llist that once IB_SEND_SIGNALED has been set is saved to tx_desc->comp_llnode_batch, and completion processing of previously posted iser_tx_descs is done in a single shot from within isert_send_completion() code. Note this is only done for response PDUs from ISCSI_OP_SCSI_CMD, and all other control type of PDU responses will force an implicit batch drain to occur.

This patch converts tcm_fc to use transport_init_session_tags() pre-allocation logic for struct ft_cmd descriptors using per-cpu session tag pooling in order to effectively avoid memory allocation + release for each received I/O. It adds percpu_ida_alloc() in ft_recv_cmd() to obtain an tag and locate ft_cmd from se_sess->sess_cmd_map[], and percpu_ida_free() in ft_free_cmd() to release the tag based upon se_cmd->map_tag id. It also uses a TCM_FC_DEFAULT_TAGS value of 512, that puts the per se_sess->sess_cmd_map allocation at ~360K on 64-bit. v2 changes: - Handle possible tag < 0 failure with GFP_ATOMIC Cc: Mark Rustad <mark.d.rustad@intel.com> Cc: Robert Love <robert.w.love@intel.com> Cc: Kent Overstreet <kmo@daterainc.com> Signed-off-by: NNicholas Bellinger <nab@daterainc.com>

From Yinghai Lu. 3) The ACPI IPMI driver sometimes attempts to acquire a mutex from interrupt context, which can be avoided by replacing that mutex with a spinlock.

Ben Herrenschmidt found that commit 928bea96 ("PCI: Delay enabling bridges until they're needed") breaks PCI in some powerpc environments. The reason is that the PCIe port driver will call pci_enable_device() on the bridge, so the device is enabled, but skips pci_set_master because pcie_port_auto and no acpi on powerpc. Because of that, pci_enable_bridge() later on (called as a result of the child device driver doing pci_enable_device) will see the bridge as already enabled and will not call pci_set_master() on it. Fixed by add checking in pci_enable_bridge, and call pci_set_master if driver skip that. That will make the code more robot and wade off problem for missing pci_set_master in drivers.

So we are talking of several thousand cycles. Considering this enabling the lockless lockref variant would contradict the intention of the new semantics. And also some quick measurements show performance regressions of 50% and more. Simply removing the cpu_relax() call again seems also not very desireable since Waiman Long reported that for some workloads the call improved performance by 5%." * 'lockref' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390: enable ARCH_USE_CMPXCHG_LOCKREF lockref: use arch_mutex_cpu_relax() in CMPXCHG_LOOP() mutex: replace CONFIG_HAVE_ARCH_MUTEX_CPU_RELAX with simple ifdef
