Yeah, I eventually found it, this would be great for perf:

Another good feature of task_diag is an ability to request information
for a few processes. Currently here are two stratgies
TASK_DIAG_DUMP_ALL	- get information for all tasks
TASK_DIAG_DUMP_CHILDREN	- get information for children of a specified
			  tasks


I.e. 'perf record -a' would use that TASK_DIAG_DUMP_ALL to synthesize
PERF_RECORD_{FORK,COMM} events, we would still need some way to generate
the PERF_RECORD_MMAP entries tho.
