Docs/mm/damon/design: fix two typos

Browse Source 
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'.

@ -25,7 +25,7 @@ DAMON subsystem is configured with three layers including
- Operations Set: Implements fundamental operations for DAMON that depends on
the given monitoring target address-space and available set of
software/hardware primitives,
- Core: Implements core logics including monitoring overhead/accurach control
- Core: Implements core logics including monitoring overhead/accuracy control
and access-aware system operations on top of the operations set layer, and
- Modules: Implements kernel modules for various purposes that provides
interfaces for the user space, on top of the core layer.
@ -192,7 +192,7 @@ one page in the region is required to be checked. Thus, for each ``sampling
interval``, DAMON randomly picks one page in each region, waits for one
``sampling interval``, checks whether the page is accessed meanwhile, and
increases the access frequency counter of the region if so. The counter is
called ``nr_regions`` of the region. Therefore, the monitoring overhead is
called ``nr_accesses`` of the region. 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.
