ocelot_get_stats64() currently runs unlocked and therefore may collide with ocelot_port_update_stats() which indirectly accesses the same counters. However, ocelot_get_stats64() runs in atomic context, and we cannot simply take the sleepable ocelot->stats_lock mutex. We need to convert it to an atomic spinlock first. Do that as a preparatory change. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org> |
