[Andrew Morton]

The quilt patch titled

has been removed from the -mm tree.  Its filename was
     mm-damon-document-that-a-zero-sample_interval-is-accepted.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

damon_set_attrs() accepts sample_interval == 0.  This was reported as a
bug in v1 of this patch (rejecting it in damon_set_attrs()).  A similar
patch was already declined for the same reason: a zero interval is
intentionally supported [1].

Document the behavior instead of changing it.
