Subject[PATCH -mm 0/5] Phase 2 of task comm cleanups
Date
This is the followup work of task comm cleanups[1].

In this phase, the hard-coded 16 is replaced by either TASK_COMM_LEN or
TASK_COMM_LEN_16, to make it grepable. The difference between this two
marcos is:
- TASK_COMM_LEN
The size should be same with the TASK_COMM_LEN defined in linux/sched.h.
For the src file which can't include linux/sched.h, a macro with the
the same name is defined in this file specifically.
- TASK_COMM_LEN_16
The size must be a fixed-size 16. It may be exposed to userspace so we
can't change it.

In order to include vmlinux.h in bpf progs under sample/bpf or
tools/testing/selftests/bpf, some structs are renamed and some included
headers are removed.
