io_uring: always go async for unsupported open flags No point in issuing -> return -EAGAIN -> go async, when it can be done upfront. Signed-off-by: Dylan Yudaken <dylany@meta.com> Link: https://lore.kernel.org/r/20230127135227.3646353-5-dylany@meta.com Signed-off-by: Jens Axboe <axboe@kernel.dk>

io_uring: correct check for O_TMPFILE O_TMPFILE is actually __O_TMPFILE|O_DIRECTORY. This means that the old check for whether RESOLVE_CACHED can be used would incorrectly think that O_DIRECTORY could not be used with RESOLVE_CACHED.

io_uring: split out fixed file installation and removal Put it with the filetable code, which is where it belongs. While doing so, have the helpers take a ctx rather than an io_kiocb. It doesn't make sense to use a request, as it's not an operation on the request itself. It applies to the ring itself. Signed-off-by: Jens Axboe <axboe@kernel.dk>
