    [$] API changes for the futex robust list

    Date:
    Wed, 04 Feb 2026 17:48:10 +0000

    Description:
    The robust
    futex kernel API is a way for a user-space program to ensure that the
    locks it holds are properly cleaned up when it exits. But the API suffers
    from a number of different problems, as Andr Almeida described in a session
    in the "Gaming on
    Linux" microconference at the 2025 Linux Plumbers Conference in Tokyo.
    He had some ideas for a new API that would solve many of those problems,
    which he wanted to discuss with attendees; there is a
    difficult-to-trigger race condition that he wanted to talk about too.
