Subject: [PATCH 12/12] io_uring/kbuf: check for ring provided buffers first in recycling
Date: Wed, 20 Aug 2025 20:03:41 -0600 [thread overview]
Message-ID: <20250821020750.598432-14-axboe@kernel.dk> (raw)
In-Reply-To: <20250821020750.598432-2-axboe@kernel.dk>
This is the most likely of paths if a provided buffer is used, so offer
it up first and push the legacy buffers to later.
