If the MDB object is programmed with SWITCHDEV_OBJ_ID_HOST_MDB then you would need this gfp_t to be GFP_ATOMIC per net/bridge/br_mdb.c::__br_mdb_notify, if this is a regular SWITCHDEV_OBJ_ID_MDB then GFP_KERNEL appears to be fine.
Good point, I think I would need to do something more radical anyway, as programming anything into the MAC table calls: ocelot_mact_learn -> ocelot_mact_wait_for_completion -> readx_poll_timeout I'm thinking to move all of this into a workqueue.
