Subject: RFC: fix queue freeze and limit locking order (alt take)
Date: Mon, 6 Jan 2025 11:06:13 +0100 [thread overview]
Message-ID: <20250106100645.850445-1-hch@lst.de> (raw)
Hi all,
this is my version of Damien's "Fix queue freeze and limit locking order".
A lot looks very similar, but it was done independently based on the
previous discussion.
The changelogs are very sparse as the moment as I started it before the
holidays and just finished it enough to send it out as a RFC today.
