From 4aa42119d971603dc9e4d8cf4f53d5fcf082ea7d Mon Sep 17 00:00:00 2001 From: Jonas Dreßler Date: Tue, 6 Feb 2024 12:08:14 +0100 Subject: Bluetooth: Remove pending ACL connection attempts MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
