I write the function description here so you could give your
comments still in this version.
/*
* Set the allocation direction to bottom-up or top-down.
*/
static inline void memblock_set_bottom_up(bool enable)
{
memblock.bottom_up = enable;
}
/*
* Check if the allocation direction is bottom-up or not.
* if this is true, that said, the boot option "movablenode"
* has been specified, and memblock will allocate memory
* just near the kernel image.
*/
static inline bool memblock_bottom_up(void)
{
return memblock.bottom_up;
}
