Subject: io_uring: don't check for io_uring_fops for fixed files
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d44f554e105b0c20e5b06b9f821bef228e04d573;p=linux.git

io_uring: don't check for io_uring_fops for fixed files

We don't allow them at registration time, so limit the check for needing
inflight tracking in io_file_get() to the non-fixed path.
