can: bcm: add missing rcu list annotations and operations<\/p>\n
sashiko-bot remarked the missing use of list_add_rcu() in
\nbcm_[rx|tx]_setup() to have a proper initialized bcm_op structure
\nwhen bcm_proc_show() traverses the bcm_op’s under rcu_read_lock().<\/p>\n
To cover all initial settings of the bcm_op’s the list_add_rcu() calls
\nare moved to the end of the setup code.<\/p>\n
While at it, also fix the mirroring removal side: bcm_release() called
\nbcm_remove_op() – which frees the op via call_rcu() – on ops that were
\nstill linked in bo->tx_ops\/bo->rx_ops, without list_del_rcu() first.
\nUnlink each op with list_del_rcu() before handing it to bcm_remove_op(),
\nmatching the existing pattern in bcm_delete_tx_op()\/bcm_delete_rx_op().<\/p>\n","protected":false},"excerpt":{"rendered":"
