Current __do_fault() is awful and unmaintainable. These patches try to
sort it out by split __do_fault() into three destinct codepaths:
- to handle read page fault;
- to handle write page fault to private mappings;
- to handle write page fault to shared mappings;
I also found page refcount leak in PageHWPoison() path of __do_fault().
Kirill A. Shutemov (8):
mm, hwpoison: release page on PageHWPoison() in __do_fault()
mm: rename __do_fault() -> do_fault()
mm: do_fault(): extract to call vm_ops->do_fault() to separate
function
mm: introduce do_read_fault()
mm: introduce do_cow_fault()
mm: introduce do_shared_fault() and drop do_fault()
mm: consolidate code to call vm_ops->page_mkwrite()
mm: consolidate code to setup pte
