The annotation for __init in enable_swap_cgroup() and __initdata for really_do_swap_account produces the following warning. Which is not right, since this function is called from non-init section. This patch fixes it. LD mm/built-in.o WARNING: mm/built-in.o(.text+0x277d9): Section mismatch in reference from the function mem_cgroup_create() to the function .init.text:enable_swap_cgroup() The function mem_cgroup_create() references the function __init enable_swap_cgroup(). This is often because mem_cgroup_create lacks a __init annotation or the annotation of enable_swap_cgroup is wrong.
