Hi, This series adds the support for S3 presigned URLs that only allow HTTP GET requests. While working on this I also stumbled upon a deadlock with concurrent I/O and slipped the fix here. Over the years there was already an attempt to support these kind of URLs[1] and at least one report of a user in need of the feature[2].
Unfortunately S3 only allows a presigned URL to live up to 7 days so we can't really put an example with a stable URL on the commit message but here is a presigned URL for the archlinux cloud image[3] that will expire in ~7 days.
