• 69e68b4f0   mm: cleanup follow_page_mask() ... Browse Code »

  Cleanups:
  - move pte-related code to separate function. It's about half of the
  function;
  - get rid of some goto-logic;
  - use 'return NULL' instead of 'return page' where page can only be
  NULL;

• 4bbd4c776   mm: move get_user_pages()-related code to separate file ... Browse Code »

  mm/memory.c is overloaded: over 4k lines. get_user_pages() code is
  pretty much self-contained let's move it to separate file.

  No other changes made.
