    Linus has released the 6.19 kernel.
    "No big surprises anywhere last week, so 6.19 is out as expected - just
    as the US prepares to come to a complete standstill later today
    watching the latest batch of televised commercials."

    The most significant changes in 6.19 include
    initial support for Intel's linear
    address-space separation feature,
    support for Arm
    Memory system resource Partitioning And Monitoring,
    the listns() system call,
    a reworked restartable-sequences
    implementation,
    support for large block sizes in the ext4
    filesystem,
    some networking changes for improved
    memory safety,
    the live update orchestrator,
    and much more. See the LWN merge-window summaries (part˙1, part˙2) and the KernelNewbies 6.19 page for
    details.
