    x86/uaccess: force copy_*_user() to be inlined · e6971009
    Kees Cook authored
    As already done with __copy_*_user(), mark copy_*_user() as __always_inline.
    Without this, the checks for things like __builtin_const_p() won't work
    consistently in either hardened usercopy nor the recent adjustments for
    detecting usercopy overflows at compile time.
    
    The change in kernel text size is detectable, but very small:
    
     text      data     bss     dec      hex     filename
