Note: I identified several issues in the documentation during review, including:

• Spelling errors: "제공어야" (line 22), "천천리" (line 160)
• Grammar issues: "의미기에" (line 55) could be more natural as "의미이므로"
• Technical typos: "csf_rq" should be "cfs_rq" (line 100), "포인트" should be "포인터" (line 102)
• Style inconsistency: Mixed use of Korean and Western punctuation (line 110)

However, I was unable to store these as formal PR comments because the files were not available in the PR diff context. Please review these issues manually:

1. Line 22: 제공어야 → 제공해야
2. Line 55: 의미기에 → 의미이므로
3. Line 100: csf_rq → cfs_rq
4. Line 102: 포인트를 → 포인터를
5. Line 110: Mixed punctuation style (period after Korean text)
6. Line 160: 천천리 → 천천히

The content is technically accurate and well-structured, covering the evolution from O(n) and O(1) schedulers to CFS, with good explanations of vruntime, red-black trees, and the transition to EEVDF. The external references to IBM and opensource.com are appropriate and functional.
