TRACE EVENT ERROR: Event ice_tx_dim_work has double dereference in TP_printk: REC->q_vector->tx.tx_ring->q_index
\n WARNING: kernel\/trace\/trace_events.c:420 at test_double_dereference.cold+0x39\/0x4b<\/p>\n
this is due to extra checks added in tracing subsystem in
\ncommit b5cc230af5e5 (“tracing: Warn when an event dereferences a pointer in TP_printk()”).<\/p>\n
Printing happens long after the event was recorded, by which point
\nthe pointers may be invalid (the ring or the dim instance).
\nCopy the eight scalars into the event instead.<\/p>\n","protected":false},"excerpt":{"rendered":"
