    fuse: allow kernel to access "direct_io" files · f4975c67
    Miklos Szeredi authored
    Allow the kernel read and write on "direct_io" files.  This is
    necessary for nfs export and execute support.
    
    The implementation is simple: if an access from the kernel is
    detected, don't perform get_user_pages(), just use the kernel address
    provided by the requester to copy from/to the userspace filesystem.
