This change refactors the way op-codes are managed in the kernel to facilitate easier cherry-picking of features on downlevel kernels without incuring significant merge conflicts and op_code collisions. Signed-off-by: Alain Michaud <alainm@xxxxxxxxxxxx> --- Here is a v2 that implements the alternative way that may address your forward declaration feedback. I'm open to any of these or any other suggestions you may have to address this. include/net/bluetooth/hci_core.h | 1 + net/bluetooth/hci_sock.c | 14 +- net/bluetooth/mgmt.c | 426
