The above is the same as FUTEX_LOCK_PI, right? So, it
probably doesn't need repeating.

I've reworked this description to be:

       FUTEX_LOCK_PI2 (since Linux 5.14)
              This operation is the same as FUTEX_LOCK_PI, except that
              the clock against which timeout is measured is selectable.
              By default, the (absolute) timeout specified in timeout is
              measured againt the CLOCK_MONOTONIC clock, but if the
              FUTEX_CLOCK_REALTIME flag is specified in futex_op, then
              the timeout is measured against the CLOCK_REALTIME clock.

Is it okay?

Sounds good.

Okay. Thanks.

Cheers,

Michael
