Subject: [PATCH v1 1/1] tracing: Drop unused helper function to fix the build
Date: Mon,  9 Sep 2024 13:53:14 +0300	[thread overview]
Message-ID: <20240909105314.928302-1-andriy.shevchenko@linux.intel.com> (raw)

A helper function defined but not used. This, in particular,
prevents kernel builds with clang, `make W=1` and CONFIG_WERROR=y:

kernel/trace/trace.c:2229:19: error: unused function 'run_tracer_selftest' [-Werror,-Wunused-function]
 2229 | static inline int run_tracer_selftest(struct tracer *type)
      |                   ^~~~~~~~~~~~~~~~~~~

Fix this by dropping unused functions.

See also commit 6863f5643dd7 ("kbuild: allow Clang to find unused static
inline functions for W=1 build").
