In short, DAMON_RECLAIM with 50ms/s time quota and regions prioritization on v5.15-rc5 Linux kernel with ZRAM swap device achieves 38.58% memory saving with only 1.94% runtime overhead. For this, DAMON_RECLAIM consumes only 4.97% of single CPU time.
While it really consumes little CPU time, is it fine for `kdamond.0` to be in a D (uninterruptible sleep) state all the time while active, pushing loadavg over 1.0? Thanks. -- Oleksandr Natalenko (post-factum)
