[PATCH] mark several functions __always_inline
Arjan van de Ven <arjan@infradead.org> Mark a number of functions as 'must inline'. The functions affected by this patch need to be inlined because they use knowledge that their arguments are constant so that most of the function optimizes away. At this point this patch does not change behavior, it's for documentation only (and for future patches in the inline series) Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Arjan van de Ven <arjan@infradead.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
