And anyway the compiler can decide to not inline a function marked
inline since commit ac7c3e4ff401 ("compiler: enable
CONFIG_OPTIMIZE_INLINING forcibly") followed by commit 889b3c1245de
("compiler: remove CONFIG_OPTIMIZE_INLINING entirely").
So unless you mark it __always_inline you have no guarranty that the
compiler does what you tell it to do.
