Since 4.11 vm_operations_struct .fault has only a vm_fault parameter
and since 4.17 callback function must return vm_fault_t instead of int

struct vm_fault changed its definition before kernel 4.10, at commit
1a29d85eb0 to be more precise. This makes code compatible with pre- and
post- 4.10 kernels.

The reason to extended it is that it makes easier the identification
of a single zio object from user-space.
It is, in a way, similar to the zio_addr, but this is ascii and with
less information (indeed it can be used only locally on the same machine)

In output configuration, 0 will mean "do not change seq_num". Any other
value will be assigned to current_ctrl->seq_num

  Enumerate channels and channel-sets in sysfs

If a custom name is not assigned, DO NOT force one (like we did). Leave it
empty so that we can easily recognize this condition.

Change the sysfs 'name' attribute in order to use the proper variable

ZIO_OBJ_NAME_LEN is *just* the limit for names, but sometimes we want to append
thing to a given name. Typically, index to identify the component in the
hierarchy. So this patch introduce ZIO_OBJ_NAME_FULL_LEN which should be used as
size for any string that modify the original name

In a big industrial environment we may have several different ZIO devices
each of them compiled with a different version of ZIO. With this versioning
field we can check che compatibility among devices and ZIO framework.

This avoid to recompile everytime all device drivers for each change.
