Subject: ocfs2: fix panic on kfree(xattr->name)
From: Tetsuo Handa <penguin-kernel@xxxxxxxxxxxxxxxxxxx>
commit f81c20158f8d5f7938d5eb86ecc42ecc09273ce6 upstream.
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().
