v1: https://lore.kernel.org/lkml/20250411172207.61332-1-iii@linux.ibm.com/
v1 -> v2: Use unsigned int instead of int.
          Add a follow-up patch that changes depth to unsigned int in
          all events.

Hi,

This series changes the type of depth in all call graph events to
unsigned int.

Patch 1 fixes a size mismatch issue in ftrace_graph_ent_entry, which
causes trace-cmd on 64-bit big-endian systems to output a lot of bogus
spaces, rendering it unusable.

Patch 2 changes type of depth in all other events to unsigned int in
order to better reflect its semantics: it can only be negative
internally, but recorded values are always non-negative.

Best regards,
Ilya
