From d5dbac87b4343d98ae509fb787efb77f8ddc484b Mon Sep 17 00:00:00 2001 From: Nishanth Aravamudan Date: Mon, 17 Dec 2007 16:20:25 -0800 Subject: Documentation: update hugetlb information The hugetlb documentation has gotten a bit out of sync with the current code. Updated the sysctl file to refer to Documentation/vm/hugetlbpage.txt. Update that file to contain the current state of affairs (with the newer named sysctl in place).
