In attempt to reduce the amount of unnecessary shost_lock acquisitions in the lpfc driver, change load_flag into an unsigned long bitmask and use clear_bit/test_bit bitwise atomic APIs instead of reliance on shost_lock for synchronization. Also, correct the test for FC_UNLOADING in lpfc_ct_handle_mibreq, which incorrectly tests vport->fc_flag rather than vport->load_flag. Signed-off-by:

In attempt to reduce the amount of unnecessary shost_lock acquisitions in the lpfc driver, replace shost_lock with an explicit fc_nodes_list_lock spinlock when accessing vport->fc_nodes lists. Although vport memory region is owned by shost->hostdata, it is driver private memory and an explicit fc_nodes list lock for fc_nodes list mutations is more appropriate than locking the entire shost.

There is no reason to use the shost_lock to synchronize an LLDD statistics counter. Convert all the nlp state statistic counters into atomic_t. Corresponding zeroing, increments, and reads are converted to atomic versions. Signed-off-by:

Desiring to reduce the amount of unnecessary shost_lock acquisitions in the lpfc driver, it has been determined that there is no need for shost_lock protection when retrieving fc_host port information because it is only for display to user via sysfs. Signed-off-by:

The ACQE notification event to reset congestion statistics should be moved into the specific lpfc_sli4_async_sli_evt() routine instead of being processed from the generic lpfc_sli4_async_event_proc() routine. Signed-off-by:

FPIN frequency is provided by the fabric in peer congestion notifications. Currently, the frequency is only logged in a message, but it should also be saved into the phba's cgn_fpin statistics member for proper application functionality. Signed-off-by:

The "Nodelist not empty" log message and an accompanying delay may be observed when deleting an NPIV port or unloading the lpfc driver. This can occur due to receipt of an ABTS for which there is no corresponding login context or ndlp allocated. In such cases, the driver allocates a new ndlp object to send a BLS_RJT after which the ndlp object unintentionally remains in the NLP_STE_UNUSED_NODE state forever. Add a check to conditionally remove ndlp's initial reference count when queuing a BLS response. If the initial reference is removed, then set the NLP_DROPPED flag to notify other code paths.

Requests to delete an NPIV port may fail repeatedly if the initial request is received during discovery. If the FC_UNLOADING load_flag is set, then skip CT response processing for the physical port. This allows discovery processing for other lpfc_vport objects to reach their cmpl routines before deleting the vport. Signed-off-by:

Upon first RSCN receipt of a target server's remote port that is initially acting as an initiator function, the driver marks the ndlp->nlp_type as an initiator role. Then later, when processing an RSCN for a target function role switch, that ndlp remote port is permanently stuck as an initiator role and can never transition to be discovered as an updated target role function. Remove the NLP_RCV_PLOGI early return if statement clause so that the NLP_NPR_2B_DISC flag gets set. This allows for role change detections. Signed-off-by:

Remove the early return NLP_FABRIC check in lpfc_plogi_confirm_nport() because it is possible for switch domain controllers to change WWPN. As a result, allow lpfc_plogi_confirm_nport() to detect that a new ndlp should be initialized in such cases. The old ndlp object will be cleaned up when dev_loss_tmo callbk executes. Signed-off-by:

D_ID swaps are common during cable swaps in a SAN. Thus, there's no reason to log the event at a KERN_ERR level with the trace event logger. Change the log level to KERN_INFO and the normal LOG_ELS flag. Signed-off-by:

The call to lpfc_sli4_resume_rpi() in lpfc_rcv_padisc() may return an unsuccessful status. In such cases, the elsiocb is not issued, the completion is not called, and thus the elsiocb resource is leaked. Check return value after calling lpfc_sli4_resume_rpi() and conditionally release the elsiocb resource. Signed-off-by:

A static code analyzer tool indicates that the local variable called status in the lpfc_sli4_repost_sgl_list() routine could be used to print garbage uninitialized values in the routine's log message. Fix by initializing to zero. Signed-off-by:

bcachefs btree nodes are big - typically 256k - and btree roots are pinned in memory. As we're now up to 18 btrees, we now have significant memory overhead in mostly empty btree roots. And in the future we're going to start enforcing that certain btree node boundaries exist, to solve lock contention issues - analagous to XFS's AGIs. Thus, we need to start allocating smaller btree node buffers when we can. This patch changes code that refers to the filesystem constant c->opts.btree_node_size to refer to the btree node buffer size - btree_buf_bytes() - where appropriate. Signed-off-by:
