Subject: [PATCH sched_ext/for-7.2] sched_ext: Mark !CONFIG_EXT_SUB_SCHED dummy stubs static inline
Date: Mon, 11 May 2026 11:41:02 -1000 [thread overview]
Message-ID: <0d690b2a5b4497032ad19f61e4574566@kernel.org> (raw)
Mark !CONFIG_EXT_SUB_SCHED dummy stubs static inline to avoid
-Wunused-function in configs without callers. No functional change.
