Subject: [PATCH v5 5/6] mm/thp: fix doc for transparent huge zero page
Date: Fri, 21 Jun 2013 08:28:53 +0800	[thread overview]
Message-ID: <1371774534-4139-5-git-send-email-liwanp@linux.vnet.ibm.com> (raw)
In-Reply-To: <1371774534-4139-1-git-send-email-liwanp@linux.vnet.ibm.com>

Transparent huge zero page is used during the page fault instead of
in khugepaged.

# ls /sys/kernel/mm/transparent_hugepage/
defrag  enabled  khugepaged  use_zero_page
# ls /sys/kernel/mm/transparent_hugepage/khugepaged/
alloc_sleep_millisecs  defrag  full_scans  max_ptes_none  pages_collapsed  pages_to_scan  scan_sleep_millisecs

This patch corrects the documentation just like the codes done.
