Oliver Hartkopp 4b07ce83e9 can: statistics: use atomic access in hot path ... [ Upstream commit 80b5f90158d1364cbd80ad82852a757fc0692bf2 ] In can_send() and can_receive() CAN messages and CAN filter matches are counted to be visible in the CAN procfs files. KCSAN detected a data race within can_send() when two CAN frames have been generated by a timer event writing to the same CAN netdevice at the same time. Use atomic operations to access the statistics in the hot path to fix the KCSAN complaint.
