This will be a growing patch-set of conversions and dead-code removal
towards the goal of retiring hci_request.c
The patch sets will be split amoung the work queues and delayed work
queues as initialized in hci_request_setup(), with the ultimate goal of
eliminating hci_request.c entirely.
v2: Published
v3: Continuing work. This does include one conversion
(SCO configure_datapath) that has been tested with mgmt-tester and
sco-tester, but has not been tested with a controller with an
off-loadable codec.
v4: Clean-up checkpatch warnings.
v5: Remove remaining procedures from hci_request.c/h. Not that other
entities (notably amp.c, hci_event.c and hci_core.c) are still using
the hci_request mechanism, however, the mgmt-tester unit test only
currently execute opcode 0x1408 - HCI_OP_READ_ENC_KEY_SIZE during normal
testing.
v6: Fix CI reported errors, and recoded hci_abort_conn for optional sync
queue usage to fix some L2CAP test cases.
v7: Delete and rebase to remove conflicting interleave scan clean-up.
Will be done using work Luiz has been working on.
Brian Gix (9):
Bluetooth: Convert le_scan_disable timeout to hci_sync
Bluetooth: Rework le_scan_restart for hci_sync
Bluetooth: Delete unused hci_req_stop_discovery()
Bluetooth: Convert SCO configure_datapath to hci_sync
Bluetooth: Move Adv Instance timer to hci_sync
Bluetooth: Delete unreferenced hci_request code
Bluetooth: move hci_get_random_address() to hci_sync
Bluetooth: convert hci_update_adv_data to hci_sync
Bluetooth: Convert hci_abort_conn to hci_sync

The le_scan_disable timeout was being performed on the deprecated
hci_request.c mechanism. This timeout is performed in hci_sync.c

le_scan_restart delayed work queue was running as a deprecated
hci_request instead of on the newer thread-safe hci_sync mechanism.

From: Brian Gix @ 2022-08-05 23:42 UTC (permalink / raw)
To: linux-bluetooth; +Cc: marcel, luiz.dentz, brian.gix
This patch deletes a whole bunch of code no longer reached because the
functionality was recoded using hci_sync.c

From: Brian Gix @ 2022-08-05 23:42 UTC (permalink / raw)
To: linux-bluetooth; +Cc: marcel, luiz.dentz, brian.gix
This function has no dependencies on the deprecated hci_request
mechanism, so has been moved unchanged to hci_sync.c
