From 2661e6c45625abd32d6447cafb8d9b99839ce408 Mon Sep 17 00:00:00 2001 From: Li Xi Date: Sun, 1 Feb 2015 21:52:03 -0500 Subject: [PATCH] staging/lustre/libcfs: fix illegal page access of tracefiled() After failure happens and put_pages_back() returns the pages, tracefiled() should not go on itering on the page list. Otherwise, some pages might be accessed illegally.
