Used yesterday and today. Seems fine. Just in quick test, I see
sometimes PSI memory spike over 40, but - important thing - no effect
on interactivity. So I didn't investigated more.

Well, just to be sure. I compiled the latest git with -rc6 and
test3_em_shrinker_6.10. Nothing more about patches.

Anyway, just for the record:
kernel: test3
       fresh: 0:03:44 [ 241MiB/s]
       aged: 0:02:07 [ 801MiB/s]
       funny thing: next runs of aged no more than  0:03:22 [
504MiB/s] (but, as I wrote, no problem with interaction).

Ok, recompile now and test!
