As Linus has pointed out, because of GCC not sharing stack among different inlined functions, the above is surprisingly not true. In kernel it's a problem due to raw stack usage. In userspace apps (where stack used is larger), inlining single-call functions could, paradoxically, run slower due to increased stack dcache pressure for some larger functions. -- Jamie -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
