From efeacc2cb6b7a0f44757d7d50069189d592c2d5c Mon Sep 17 00:00:00 2001 From: SeongJae Park Date: Mon, 1 Jul 2024 12:26:58 -0700 Subject: [PATCH] Docs/mm/damon/design: fix two typos Patch series "Docs/damon: minor fixups and improvements". Fixup typos, clarify regions merging operation design with recent change, add access pattern snapshot example use case, and improve readability of the design document and subsystem documents index by reorganizing/wordsmithing and adding links to other sections and/or documents for easy browsing. This patch (of 9): Fix two typos. The first one is just a simple typo: s/accurach/accuracy/ The second one is made by the author being out of their mind. 'Region Based Sampling' section of the doc is mistakenly calling the access frequency counter of region as 'nr_regions'. Fix it with the correct name, 'nr_accesses'.

Therefore, the monitoring overhead is controllable by setting the number of regions. DAMON allows users to set the minimum and the maximum number of regions for the trade-off.
