lttng-modules-dkms fails to build on 5.19 with the following error:

  133 | void trace_##_name(_proto);
      |      ^~~~~~

[Test case]

$ sudo apt install lttng-modules-dkms

[Fix]

Support the new prototype of mm_page_alloc_zone_locked() introduced in
5.19.

[Regression potential]

We may experience regressions using lttng on kernels >= 5.19, especially
when tracing memory-related events.
