[V2 that should apply cleanly on current HEAD]
Hi Jens, I've spotted a regression on a fast SSD: a loss of I/O-latency control with interactive tasks (such as the application start up I usually test). Details in the commit.
I do hope that, after proper review, this commit makes it for 5.3.
Thanks, Paolo
