    [$] Page allocation for address-space isolation

    Description:
    Address-space isolation may well be, as Brendan Jackman said at the
    beginning of his memory-management-track session at the 2025 Linux Storage, Filesystem, Memory-Management, and BPF Summit, " some security
    bullshit ". But it also holds the potential to protect the kernel from
    a wide range of vulnerabilities, both known and unknown, while reducing the impact of existing mitigations. Implementing address-space isolation with reasonable performance, though, is going to require some significant
    changes. Jackman was there to get feedback from the memory-management community on how those changes should be implemented.
