Name:trace_print_lat_context

Proto:int trace_print_lat_context(struct trace_iterator *iter)

Type:int

Parameter:

TypeParameterName
struct trace_iterator *iter
620  tr = tr
622  ent_size = ent_size
623  s = The below is zeroed out in pipe_read
625  entry = ent , next_entry = Find the next real entry, without updating the iterator itself
628  verbose = trace_flags & TRACE_ITER_VERBOSE
631  ent_size = ent_size
633  If Not next_entry Then next_ts = ts
636  If verbose Then
639  trace_find_cmdline(pid, comm)
641  Currently only defined when tracing is enabled.
645  Else
646  lat_print_generic(s, entry, cpu)
649  lat_print_timestamp(iter, next_ts)
651  Return Not race_seq_has_overflowed - return true if the trace_seq took too much*@s: trace sequence descriptor* Returns true if too much data was added to the trace_seq and it is* now full and will not take anymore.
