In order to access the data of the hypfs diagnose calls from user space also in binary form, this patch adds two new attributes in debugfs: * z/VM: s390_hypfs/d2fc_bin * LPAR: s390_hypfs/d204_bin Signed-off-by: Michael Holzheu <holzheu@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
