arm64: stacktrace: rename unwind_next_common() -> unwind_next_frame_record()
The unwind_next_common() function unwinds a single frame record. There are other unwind steps (e.g. unwinding through trampolines) which are handled in the regular kernel unwinder, and in future there may be other common unwind helpers. Clarify the purpose of unwind_next_common() by renaming it to unwind_next_frame_record(). At the same time, add commentary, and delete the redundant comment at the top of asm/stacktrace/common.h. There should be no functional change as a result of this patch. Signed-off-by: Mark Rutland <mark.rutland@arm.com> Reviewed-by: Kalesh Singh <kaleshsingh@google.com> Reviewed-by: Madhavan T.
