memfd_create() handles all of its logic in a single function. Some of
the logic in the function is also somewhat contrived (i.e. copying the
memfd name from userpace).

This series aims to cleanup memfd_create() by splitting out the logic
into helper functions, and simplifying the memfd name copying to make
the code easier to follow.

This has no intended functional changes.

Changes from v1 ==> v2:

- Rebased on top of the mm-unstable branch instead of Linus' master
  branch. Base commit on mm-unstable: ca95745c20ad ("mm/memmap: prevent
  double scanning of memmap by kmemleak").
