[for-linus][PATCH 0/4] tracing: More fixes for v6.8

More fixes for 6.8

- Fix a false positive kmemleak on saved cmdlines
Now that the saved_cmdlines structure is allocated via alloc_page()
and not via kmalloc() it has become invisible to kmemleak.
The allocation done to one of its pointers was flagged as a
dangling allocation leak. Make kmemleak aware of this allocation
and free.

- Fix synthetic event dynamic strings.
A update that cleaned up the synthetic event code removed the
return value of trace_string(), and had it return zero instead
of the length, causing dynamic strings in the synthetic event
to always have zero size.

- Clean up documentation and header files for seq_buf
