Re: [PATCH 05/15] Add io_uring IO interface

Jens,

I bit the bullet and bumped the size. 64 bytes is a nicer size in terms
of cachelines anyway, and I really doubt that 48 vs 64 bytes makes a
size consumption problem for anyone.

The buf_index is only used for the fixed buffers, which means that we have
16 bytes / 128 bits that we can grab for things like KV.

Great!
