From d0528b5d71faf612014dd7672e44225c915344b2 Mon Sep 17 00:00:00 2001 From: Joshua Zhu Date: Sat, 5 Jan 2013 13:29:57 +0800 Subject: [PATCH] perf tools: Add anonymous huge page recognition 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.
