Date: Wed, 23 Oct 2024 09:59:50 -0600	[thread overview]
Message-ID: <20241023160105.1125315-1-axboe@kernel.dk> (raw)

Hi,

Here's v2 of the ring resizing support. For the v1 posting and details,
look here:

Since v1:
- For SINGLE_ISSUER, limit resize task to owning task
- Fail the resize if the operation would result in CQ or SQ overflow
- Expand liburing test cases quite a bit
