With the last commit we moved to using the hci_sync queue for "Create Connection" requests, removing the need for retrying the paging after finished/failed "Create Connection" requests and after the end of inquiries. hci_conn_check_pending() was used to trigger this retry, we can remove it now. Note that we can also remove the special handling for COMMAND_DISALLOWED errors in the completion handler of "Create Connection", because "Create Connection" requests are now always serialized. This is somewhat reverting commit 4c67bc74f016 ("[Bluetooth] Support concurrent connect requests"). With this, the BT_CONNECT2 state of ACL hci_conn objects should now be back to meaning only one thing: That we received a "Connection Request" from another device (see hci_conn_request_evt), but the response to that is going to be deferred. --- include/net/bluetooth/hci_core.h | 1 - net/bluetooth/hci_conn.c | 16 ---------------- net/bluetooth/hci_event.c | 21 ++++----------------- 3 files changed, 4 insertions(+), 34 deletions(-)
