yes, your patch set totally fixes the regression.
our bot automatically fetch the patch set and apply it upon mainline
d4560686726f7 as below.

d4560686726f7 (HEAD, linus/master) Merge tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost
I tested patch set tip d58de4f958df2 as well as d4560686726f7, below is the
results combining with 8be7258aad and its parent.
data from 8be7258aad and d4560686726f7 are close enough to within the noise.
the patch set tip recover the performance to the level of ff388fe5c4.
