    mm: kill vma flag VM_CAN_NONLINEAR · 0b173bc4
    Konstantin Khlebnikov authored
    Move actual pte filling for non-linear file mappings into the new special
    vma operation: ->remap_pages().
    
    Filesystems must implement this method to get non-linear mapping support,
    if it uses filemap_fault() then generic_file_remap_pages() can be used.
    
    Now device drivers can implement this method and obtain nonlinear vma support.
