title: Linux kernel variables ending in 'i' meaning
body: <p>It's a random and stupid question, but I have no clue what the i stands for in structs with members like:</p>
  <p><code>[starting character]i_[some specifier]</code></p>
  <p>Examples are like: <a href="https://elixir.bootlin.com/linux/v5.17.2/source/include/linux/blk_types.h#L237" rel="nofollow noreferrer">bio struct</a>, <a href="https://elixir.bootlin.com/linux/v5.17.2/A/ident/dm_target" rel="nofollow noreferrer">everytime dm_target is referenced</a>, <a href="https://elixir.bootlin.com/linux/v5.17.2/source/include/linux/bvec.h#L38" rel="nofollow noreferrer">bvec_iter</a>.</p>
  <p>Whenever I read such a variable I read the complete name in my head, and it's very frustrating to me that I can't do it with these.</p>
