[PATCH 0/7] damos_apply_scheme() splits a region and apply the action to the

[SJ Park]

The user impact is not critical.  The failure of damon_split_region_at()
is unlikely since it is arguably too small to fail.  Also DAMOS being
aggressive is limited to the single region.  Users can set
min_nr_regions to set the maximum size of each region.  If it is
reasonably set, the transient overhead shouldn't be critical.

The issue was discovered [1] by Sashiko.
