    A strictly monotonically increasing sequence is normally used in
    numbered lists as they provide an intuitive ordering of the
    elements.

    However, in situations where race conditions can appear, this
    assumption breaks down and you can end up with unpredictable
    results, leading to a rather confusing list :-)

    This changes the numbered list 1,2,2,2 to the more intuitive
    1,2,3,4.

  • 26c369dad   futex: documentation: fix inconsistent description of futex list_op_pending ... Browse Code »

    Strictly speaking list_op_pending points to the 'lock entry', not the
    'lock word' (which is actually at 'offset' from 'lock entry'). We can
    infer this based on reading the code in kernel/futex.c:

    struct robust_list __user *entry, *next_entry, *pending;
    ...
    if (fetch_robust_entry(&pending, &head->list_op_pending, &pip))
    return;
    ...
    if (pending)
    handle_futex_death((void __user *)pending + futex_offset,
    curr, pip);

    Which is also consistent with the rest of the docs on robust futex lists.

    This patch fixes typos in various Documentation txts. The patch addresses some
    +words starting with the letters 'U-Z'.

    Looks like I made it through the alphabet...just in time to start over again
    +too! Maybe I can fit more profound fixes into the next round...? Time will
    +tell. :)
