The littlefs allows buffers to be passed statically in the case that a system does not have a heap. Unfortunately, this means we can't round up in the case of an unaligned lookahead buffer. Double unfortunately, rounding down after clamping to the block device size could result in a lookahead of zero for block devices < 32 blocks large. The assert in littlefs does catch this case, but rounding down prevents support for < 32 block devices. The solution is to simply require a 32-bit aligned buffer with an assert. This avoids runtime problems while allowing a user to pass in the correct buffer for < 32 block devices. Rounding up can be handled at higher API levels.
