From: Tetsuo Handa <penguin-kernel@xxxxxxxxxxxxxxxxxxx> Subject: ocfs2: fix panic on kfree(xattr->name) Commit 9548906b '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().
