4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Pan Bian <bianpan2016@xxxxxxx> commit 6c370590cfe0c36bcd62d548148aa65c984540b7 upstream. In function xfs_test_remount_options(), kfree() is used to free memory allocated by kmem_zalloc(). But it is better to use kmem_free().
