## Why it's here

Surfaced by the search "Linux relatime lazytime atime update reduce write overhead filesystem technique" as LWN's own historical coverage of the atime/relatime kernel discussion; the Red Hat documentation (`redhat-relatime-drive-access.md`) was used as the Tier 1 source for the actual relatime/lazytime mechanics instead of this article, which was not independently opened.
