This is a note to let you know that I have just added a patch titled perf tools: Add anonymous huge page recognition 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 b6d79ce764f9fb5e3df248d23bc733b3c626f228 Mon Sep 17 00:00:00 2001 From: Joshua Zhu <zhu.wen-jie@hp.com> Date: Sat, 5 Jan 2013 13:29:57 +0800 Subject: [PATCH] perf tools: Add anonymous huge page recognition commit d0528b5d71faf612014dd7672e44225c915344b2 upstream. Judging anonymous memory's vm_area_struct, perf_mmap_event's filename will be set to "//anon" indicating this vma belongs to anonymous memory. Once hugepage is used, vma's vm_file points to hugetlbfs. In this way, this vma will not be regarded as anonymous memory by is_anon_memory() in perf user space utility.
