[PATCH] ftrace: Fix type of ftrace_graph_ent_entry.depth
From: Ilya Leoshkevich <iii@linux.ibm.com>
Date: 2025-04-11 17:22:20
Also in:
lkml
Subsystem:
the rest, tracing · Maintainers:
Linus Torvalds, Steven Rostedt, Masami Hiramatsu
ftrace_graph_ent.depth is int, but ftrace_graph_ent_entry.depth is
unsigned long. This confuses trace-cmd on big-endian systems and makes
it print a huge amount of spaces. Make the types match.
Fixes: ff5c9c576e75 ("ftrace: Add support for function argument to graph tracer")
