# commit 490fc053865c9cc40f1085ef8a5504f5341f79d2
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Sat Jul 21 15:24:03 2018 -0700
# 
#     mm: make vm_area_alloc() initialize core fields
#     
#     Like vm_area_dup(), it initializes the anon_vma_chain head, and the
#     basic mm pointer.
#     
#     The rest of the fields end up being different for different users,
#     although the plan is to also initialize the 'vm_ops' field to a dummy
#     entry.
#
