I know. We don't hide it, BTW, you have to explicitly set it up. The simple fact is that the vast majority of V4L2 drivers need to serialize ioctl calls anyway. This is usually implemented pretty badly.

Another reason for doing this was the BKL removal were we needed something reasonably simple to convert old (usually unmaintained) drivers without having to do extensive code reviews.

Understood, that all makes sense, sorry if I sounded critical. You've put in a lot of work and, as a result, V4L2 has gotten a lot better in the time I've been paying attention to it.
