[SCSI] lpfc 8.3.21: Critical Errors and Bug Fixes
Critical Errors: - Correctly handle non-zero return lpfc_workq_post_event and return ENOMEM - Save the irq level when locking the host_lock in lpfc_findnode_did Bug Fixes: - Adjust payload_length and request_length for sli4_config mailbox commands. - Add the freed sgl/XRI to the tail of the list rather than to the head. - Set the FC_VPORT_NEEDS_INIT_VPI on vport deletes and check it before issuing a fdisc on an els retry. - Only call lpfc_hba_init_link() if phba->cfg_suppress_link_up is LPFC_INITIALIZE_LINK. - Add support for SLI-4 Performance Hints Signed-off-by: Alex Iannicelli <alex.iannicelli@emulex.com> Signed-off-by: James Smart <james.smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
