Good idea, though.. I wanted to set it for the whole "disk"(array)
as it (multiple 4T drives) will be subdivided into multiple filesystems
and have lvm and a partition table under the file system(s),
so telling the kernel to only do 4K alloc+io's to the whole thing
would cover the most with the least.
