Subject: [PATCH 30/33] [scsi] scsi: mpt3sas: Add bypass_dirty_port_flag
parameter
Message-id: <20201113184258.11169-12-thenzl@redhat.com>
Patchwork-id: 339467
Patchwork-instance: patchwork
O-Subject: [RHEL8.4 e-stor PATCH 11/14] scsi: mpt3sas: Add bypass_dirty_port_flag parameter
Bugzilla: 1888543
RH-Acked-by: Ewan Milne <emilne@redhat.com>
RH-Acked-by: Tony Camuso <tcamuso@redhat.com>
Added a new parameter bypass_dirty_port_flag in function
mpt3sas_get_port_by_id(). When this parameter is set to one then search for
matching hba port entry from port_table_list even when this hba_port entry
is marked as dirty.
