From c020395b6634b7a674ee6aa91a971b08e268caba Mon Sep 17 00:00:00 2001 From: Marco Elver Date: Tue, 26 Nov 2019 15:04:04 +0100 Subject: asm-generic/atomic: Use __always_inline for pure wrappers Prefer __always_inline for atomic wrappers. When building for size (CC_OPTIMIZE_FOR_SIZE), some compilers appear to be less inclined to inline even relatively small static inline functions that are assumed to be inlinable such as atomic ops. This can cause problems, for example in UACCESS regions. By using __always_inline, we let the real implementation and not the wrapper determine the final inlining preference. For x86 tinyconfig we observe: - vmlinux baseline: 1316204 - vmlinux with patch: 1315988 (-216 bytes) This came up when addressing UACCESS warnings with CC_OPTIMIZE_FOR_SIZE in the KCSAN runtime: http://lkml.kernel.org/r/58708908-84a0-0a81-a836-ad97e33dbb62@infradead.org Reported-by: Randy Dunlap Signed-off-by: Marco Elver Acked-by: Mark Rutland Signed-off-by: Paul E.
