strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
We can see that client->name should be NUL-terminated based on its usage
with a %s C-string format specifier.
| client->thread = kthread_run(ioreq_task, client, "VM%u-%s",
| client->vm->vmid, client->name);
NUL-padding is not required as client is already zero-allocated:
| client = kzalloc(sizeof(*client), GFP_KERNEL);
Considering the above, a suitable replacement is `strscpy` [2] due to
the fact that it guarantees NUL-termination on the destination buffer
without unnecessarily NUL-padding.
Note that this patch relies on the _new_ 2-argument version of strscpy()
