MEMORY MAPPING does not list the mmap.h trace point file, but does list
the mmap.c file. Couple the trace points with the users and authors of
the trace points for notifications of updates.

Should mmap_lock.h also be added here?

Oh, well..
mmap_lock.h (include/trace/events/mmap_lock.h) has to do with
mm/mmap_lock.c, which also isn't listed here. Both exist for tracing as
well.
There is also include/linux/mmap_lock.h, which is the locking itself.
The mmap lock is used more broadly than just these files: mm/pagewalk.c
and mm/ksm.c, for instance.
So I guess that's a more difficult decision.
Thanks for bringing this up,
Liam

Makes perfect sense. Thank you for kindly clarifying this.
