    [XFS] Keep stack usage down for 4k stacks by using noinline. · 7989cb8e
    David Chinner 提交于
    gcc-4.1 and more recent aggressively inline static functions which
    increases XFS stack usage by ~15% in critical paths. Prevent this from
    occurring by adding noinline to the STATIC definition.
    
    Also uninline some functions that are too large to be inlined and were
    causing problems with CONFIG_FORCED_INLINING=y.
    
    Finally, clean up all the different users of inline, __inline and
    __inline__ and put them under one STATIC_INLINE macro. For debug kernels
    the STATIC_INLINE macro uninlines those functions.
