    Seven new stable kernels

    [$] Auditing io_uring
    The io_uring subsystem, first introduced in
    2019, has quickly become the leading way to perform high-bandwidth,
    asynchronous I/O. It has drawn the attention of many developers, including,
    more recently,
    those who are focused more on security than performance. Now some members
    of the security
    community are lamenting a perceived lack of thought about security support in
    io_uring, and are trying to remedy that shortcoming by adding audit and
    Linux security module support there. That process is proving difficult,
    and has raised the prospect of an unpleasant fallback solution.
