This patchset is part of the patchset "extend task comm from 16 to 24"[1].
Now we have different opinion that dynamically allocates memory to store 
kthread's long name into a separate pointer, so I decide to take the useful
cleanups apart from the original patchset and send it separately[2].

These useful cleanups can make the usage around task comm less
error-prone. Furthermore, it will be useful if we want to extend task
comm in the future.

All of the patches except patch #4 have either a reviewed-by or a
acked-by now. I have verfied that the vmcore/crash works well after
patch #4.
