From f3d40e6545594c22733d091c5ec6b8ff345cbd57 Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Google)" Date: Tue, 20 Jun 2023 18:34:55 -0400 Subject: [PATCH] fgraph: Add declaration of "struct fgraph_ret_regs" MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit In final testing of: https://patchwork.kernel.org/project/linux-trace-kernel/patch/1fc502712c981e0e6742185ba242992170ac9da8.1680954589.git.pengdonglin@sangfor.com.cn/ "function_graph: Support recording and printing the return value of function" The test failed due to a new warning found in the build: kernel/trace/fgraph.c:243:56: warning: ‘struct fgraph_ret_regs’ declared inside parameter list will not be visible outside of this definition or declaration Instead of asking to send another patch series, just add it and then apply the updates.
