    I've got it. I'm backporting the dma-buf (drivers/base/dma-buf.c)
    feature to kernels < 3.3. It is actually pretty straightforward except
    a single call to get_unused_fd_flags() from dma_buf_fd(). Then
    get_unused_fd_flags() macro resolves to alloc_fd() which is not
    exported.

    Maybe I should backport alloc_fd and rename it to sth like
    compat_alloc_fd and use that instead of alloc_fd in compat. What I was
    trying to understand was the reason behind exporting/not-exporting
    those similar wrappers. I don't try to justify that it should be
    exported for me :)

    Thanks!
