Hi Martin,
> The current wait algorithm for filling the cache after readahead()
> will never retry if the cache doesn't start filling within 15ms.
> Rewrite the wait loop to always allow at least 100ms for the cache
> to fill and exit early only if cache increased by at least half
> of the expected amount. This fixes random test failures if the interval
> between cache increases is longer than 5ms.
LGTM, merged. Thank you.
Kind regards,
Petr
