From c759e609030ca37e59866cbc849fdc611cc56292 Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Google)" Date: Fri, 23 Feb 2024 15:22:06 -0500 Subject: tracing: Remove __assign_str_len() Now that __assign_str() gets the length from the __string() (and __string_len()) macros, there's no reason to have a separate __assign_str_len() macro as __assign_str() can get the length of the string needed. Also remove __assign_rel_str() although it had no users anyway.
