But gdb shows me:

(gdb) l *(ath_tx_start+0xa6)
0x22d06 is in ath_tx_start (include/trace/events/kmem.h:47).
42              {(unsigned long)__GFP_THISNODE,

43              {(unsigned long)__GFP_RECLAIMABLE,
"GFP_RECLAIMABLE"},     \
44              {(unsigned long)__GFP_MOVABLE,          "GFP_MOVABLE"}
         \
45              ) : "GFP_NOWAIT"

47      TRACE_EVENT(kmalloc,

51                       size_t bytes_req,

But I don't have the mac80211 tracer enabled.
