Subject: Where in the code mmap + MAP_ANONYMOUS clears returned pages?

Guys,

I look into mmap.c code [1] and try to understand where anonymous
memory mapping (mmap + MAP_ANONYMOUS) sets memory to zero. My best
guess is I should dig that somewhere in mmap_region.

Could you please help me locating the code which makes returned memory
pages clean? Thank you in advance.
