[PATCH] ftrace: makes ops_references_rec() inline

From: Kuninori Morimoto
Date: Tue Aug 09 2022 - 19:57:06 EST



commit 53cd885bc5c3e ("ftrace: Allow IPMODIFY and DIRECT ops on the
same function") removes "inline" from ops_references_rec(),
thus we will get below error if .config doesn't have CONFIG_MODULES.

CC kernel/trace/ftrace.o
${linux}/kernel/trace/ftrace.c:3149:1: error: 'ops_references_rec' \
defined but not used [-Werror=unused-function]
3149 | ops_references_rec(struct ftrace_ops *ops, struct dyn_ftrace *rec)
| ^~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
make[2]: *** [${linux}/scripts/Makefile.build:249: kernel/trace/ftrace.o] error 1
make[1]: *** [${linux}/scripts/Makefile.build:466: kernel/trace] error 2
make: *** [/opt/disk_cd/morimoto/linux/Makefile:1843: kernel] error 2

This patch adds "inline" again, and fixes the issue.
