From f81c20158f8d5f7938d5eb86ecc42ecc09273ce6 Mon Sep 17 00:00:00 2001 From: Tetsuo Handa Date: Thu, 3 Apr 2014 14:47:07 -0700 Subject: [PATCH] ocfs2: fix panic on kfree(xattr->name) Commit 9548906b2bb7 ('xattr: Constify ->name member of "struct xattr"') missed that ocfs2 is calling kfree(xattr->name). As a result, kernel panic occurs upon calling kfree(xattr->name) because xattr->name refers static constant names. This patch removes kfree(xattr->name) from ocfs2_mknod() and ocfs2_symlink().
