Another day, another spin. This is v14, and it fixes a few silly
issues with fsync, mainly, but also various little fixes and tweaks
all over the map.

The liburing git repo has a full set of man pages for this, though they
could probably still use a bit of polish. I'd also like to see a
io_uring(7) man page to describe the overall design of the project,
expect that in the not-so-distant future. You can clone that here:

git://git.kernel.dk/liburing

Patches are against 5.0-rc5, and can also be found in my io_uring branch
here:

git://git.kernel.dk/linux-block io_uring


Changes since v13:
- Use READ/WRITE_ONCE anywhere we touch the shared data
- Cache if we need to account/unaccount memory
- Fix fsync file grabbing
- Fix oops with fsync and deferred async list
- Fix final fput() of fixed files AFTER adding to socket
- Use correct iterator to free fixed user bufs
- up/down_read() for mmap_sem when mapping buffers
- completion -> complete in Kconfig help entry
- Ensure malicious app can't trick NOP into leaking a file
- Add a few comments, address a few review comments
