![]() When allocating a new pool at runtime, reduce the number of slabs so
that the allocation order is at most MAX_ORDER. This avoids a kernel
warning in __alloc_pages().
The warning is relatively benign, because the pool size is subsequently
reduced when allocation fails, but it is silly to start with a request
that is known to fail, especially since this is the default behavior if
the kernel is built with CONFIG_SWIOTLB_DYNAMIC=y and booted without any
swiotlb= parameter.
