This series addresses the remaining rpm issues that I'm aware of.

Jens: Once the patches are merged and you publish a 0.1 release tag I could
roll the first liburing rpm for Fedora.  liburing itself is in good shape for
wider consumption but maybe it makes sense to wait for kernel issues to settle.
There are qemu-iotests failures that are probably kernel bugs (hopefully known
ones!) and will be investigated soon.

rpmlint spotted that the LGPL v2.1 license file is outdated so I've
replaced it with the latest one from
https://www.gnu.org/licenses/old-licenses/lgpl-2.1.txt.

The Free Software Foundation address is outdated in COPYING and the file
still mentions LGPL v2 where the latest text mentions v2.1:

     This library is free software; you can redistribute it and/or
     modify it under the terms of the GNU Lesser General Public

I'm not sure if the v2 vs v2.1 issue matters to the copyright holders of
liburing.  The reason I am posting this patch is to make rpmlint happy
but we could leave the file unchanged if you prefer.

website/documentation.  Since liburing does not have a landing page,
point to the cgit page where all information can be found.

There are two issues with the <liburing/*.h> headers:
1. They are installed with 0755 permissions.
2. The empty /usr/include/liburing/ directory is left behind by rpm -e.

Fix this by specifying the directory (not just globbing the files inside
it) and letting rpm use the default permissions on these files.

Applied all 4, thanks.

Any pointers to the qemu-iotests failures?

It's due to how XFS handles (or doesn't handle) REQ_NOWAIT. I've got
a patch for this that needs some testing, but I probably won't get to
this until Monday, currently out on vacation until Sunday.
