From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx>
Here is -v4 series code to add target_alloc_session() helper
support using existing percpu-ida tag pre-allocation logic,
along with a new (*callback)() for allowing fabric driver
code to finish setup ahead of transport_register_session()
I_T nexus creation completion.
This includes a tree-wide fabric driver conversion to use
target_alloc_session() + associated (*callback)() within
common code. It updates lookback, vhost/iscsi, tcm_qla2xxx,
tcm_fc, usb-gadget, ib_srpt, sbp-target, and xen-scsiback
to use the new alloc_session callback for internal nexus
related assignments.
As per HCH, it also updates sbp-target, usb-gadget, ib_srpt
and xen-scsiback to support modern percpu_ida pre-allocation
ot se_cmd tags, along with TARGET_SCF_ACK_KREF conversions
of tcm_fc, sbp-target, usb-gadget, and xen-scsiback for
v4.6-rc1 code.
v4 changes:
- usb-gadget: Add alloc_session callback for fabric nexus assignment
(Andrzej Pietrasiewicz)
- usb-gadget: Add USB_G_DEFAULT_SESSION_TAGS=128
- usb-gadget: Fix missing percpu_ida tag memset
(Andrzej Pietrasiewicz + nab)
- sbp-target: Add missing percpu_ida tag memset (Chris Boot)
- sbp-target: Drop debug from mgmt request alloc (Chris Boot)
- loopback: Convert nexus assignments to alloc_session callback
- usb-gadget: Convert nexus assignments to alloc_session callback
(Andrzej Pietrasiewicz)
- xen-scsiback: Convert nexus assignments to alloc_session callback
- xen-scsiback: Add VSCSI_DEFAULT_SESSION_TAGS=128
Thank you,
