This is a note to let you know that I have just added a patch titled tracing: Fix off-by-one on allocating stat->pages to the linux-3.5.y-queue branch of the 3.5.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 21c705b8b7dc20921ce83b1302c641c8e347d2e6 Mon Sep 17 00:00:00 2001 From: Namhyung Kim <namhyung.kim@lge.com> Date: Mon, 1 Apr 2013 21:46:24 +0900 Subject: [PATCH] tracing: Fix off-by-one on allocating stat->pages commit 39e30cd1537937d3c00ef87e865324e981434e5b upstream. The first page was allocated separately, so no need to start from 0.
