Linus Torvalds 5e98e916f9 tracing: Fix showing of TASK_COMM_LEN instead of its value
The TASK_COMM_LEN was converted from a macro into an enum so that BTF
 would have access to it. But this unfortunately caused TASK_COMM_LEN to
 display in the format fields of trace events, as they are created by the
 TRACE_EVENT() macro and such, macros convert to their values, where as
 enums do not.
 
 To handle this, instead of using the field itself to be display, save the
 value of the array size as another field in the trace_event_fields
 structure, and use that instead. Not only does this fix the issue, but
 also converts the other trace events that have this same problem (but were
 not breaking tooling). With this change, the original work around
 b3bc8547d3 ("tracing: Have TRACE_DEFINE_ENUM affect trace event types
 as well") could be reverted (but that should be done in the merge window).
