218a562f273bec7731af4e713df72d2c8c8816e8 is the first bad commit
commit 218a562f273bec7731af4e713df72d2c8c8816e8

    make __set_open_fd() set cloexec state as well
    
    ->close_on_exec[] state is maintained only for opened descriptors;
    as the result, anything that marks a descriptor opened has to
    set its cloexec state explicitly.
    
    As the result, all calls of __set_open_fd() are followed by
    __set_close_on_exec(); might as well fold it into __set_open_fd()
    so that cloexec state is defined as soon as the descriptor is
    marked opened.

And reverting that commit from today's linux-next fixes my problem.
