Thank you for your contribution! Sashiko AI review found 4 potential issue(s) to consider:
- [Low] The newly added documentation file `hugepage.rst` is orphaned because it is not included in any Sphinx `toctree`.
- [Low] The documentation references an incorrect Kconfig symbol `CONFIG_DAMON_HUGEPAGE` instead of `CONFIG_SAMPLE_DAMON_HUGEPAGE`.
- [Low] Missing newline at the end of the newly added documentation file.
- [Low] Multiple spelling and grammatical errors in the newly added documentation.

commit 24c835e6a5624692adf95a519c4c1747fca62d26
Author: Asier Gutierrez <gutierrez.asier@huawei-partners.com>

Documentation/admin-guide/mm/damon: add DAMON-based Hugepage Management

Add documentation for the DAMON-based Hugepage Management
(SAMPLE_DAMON_HUGEPAGE) feature, which automatically manages
huge pages by identifying hot memory regions and collapsing
them back to regular pages.

[Severity: Low]
Is this new documentation file orphaned? It doesn't appear to be added to the
toctree in Documentation/admin-guide/mm/damon/index.rst.

[Severity: Low]
Does this reference the wrong Kconfig symbol? The module appears to be
SAMPLE_DAMON_HUGEPAGE, so should this be CONFIG_SAMPLE_DAMON_HUGEPAGE=y?

[Severity: Low]
This isn't a bug, but should "reads" be "read" here?

[Severity: Low]
This isn't a bug, but should this be "parameters that are updated"?

[Severity: Low]
This isn't a bug, but there is a typo here ("charget" -> "charge").

[Severity: Low]
This isn't a bug, but should this be "aiming to receive"?

[Severity: Low]
This isn't a bug, but there is a typo here ("collpases" -> "collapses").

[Severity: Low]
This isn't a bug, but could we add a newline at the end of the file?
