Geert noticed that there was an issue if io_uring wasn't configured, there's been a patch added for that. I'll send a v2 of this pull request.

Hi Linus, On top of the block and io_uring branches, here are a set of updates for the passthrough support that was merged in the 6.0 kernel. With these changes, passthrough NVMe support over io_uring now performs at the same level as block device O_DIRECT, and in many cases 6-8% better. This pull request contains: - Add support for fixed buffers for passthrough (Anuj, Kanchan) - Enable batched allocations and freeing on passthrough, similarly to what we support on the normal storage path (me) Please pull!
