[3f8be484] | 31 | years, the kernel developers have taken a strong stance that this |

[4f049972] | 32 | should not be done. This gave birth to the Linux-Libc-Headers Project, |

[3f8be484] | 33 | which was designed to maintain an API stable version of the Linux |

[9f08378] | 34 | headers. Recently this project stopped producing updates, so the Cross-LFS |
