    Linux: d_splice_alias may drop inode reference on error
    
    d_splice_alias now drops the inode reference on error, so we
    need to grab an extra one to make sure that the inode doesn't
    go away, and release it when done if there was no error.
    
    For kernels that may not drop the reference, provide an
    additional iput() within an ifdef.  This could be hooked up
    to a configure option to allow building a module for a kernel
    that is known not to drop the reference on error.  That hook
    is not provided here.  Affected kernels should be the early
    3.17 ones (3.17 - 3.17.2); 3.16 and older kernels should not
    return errors here.
    
    [kaduk@mit.edu add configure option to control behavior, which
    is mandatory on non-buildbot linux systems]
