[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 Paolo Valente (1): block, bfq: check also in-flight I/O in dispatch plugging block/bfq-iosched.c | 67 +++++++++++++++++++++++++++++---------------- 1 file changed, 43 insertions(+), 24 deletions(-) -- 2.20.1
