Sorry, missed this earlier. Note that there is a default_oa_buffer_size,
just below. Can we use that or we need this new buffer_fill_size variable?

The kernel will return a constant default_oa_buffer_size of 16 M (at least
for now).

We can fix this later too if needed, so not need to spin a new version for
now for this. We can do this if we see any other reason for a new version,
till now doesn't look like it.
