Hey everyone, I've recently been pinged by quite a few people about the state of the close_range() patchset. I've been sitting on this for a while because other stuff came up. Last time it was considered to be in mergeable state and I plan to send it for v5.5 since quite a bunch of projects in userspace have expressed interest in using this including Python and systemd. I've also coordinated with some FreeBSD developers who got in touch with me. FreeBSD has expressed interest in adding the same syscall once we merged it. This is a resend of the close_range() patchset (cf. [1]). I'd like to target v5.5. [1]: https://lwn.net/Articles/789023/ Thanks!
