fs/fuse kio: relax congestion avoidance limits (backport from usermode) Investigation of VZ US-QA cluster shows that congestion window reduction after idle periods results in too slow window open after data start to flow again. So, introduce ssthresh to allow faster window open after idle periods. Maybe, even this is not enough and window should be open even more aggressively. Further observations will show.
