| Description |

This Ubuntu 20.04 security-related kernel patch collides with ldiskfs patches in ext4-pdirop.patch and prevents Lustre from building:
Since it is security related and pretty isolated, I imagine the other distros will eventually cherry-pick it as well (I haven't checked the other distros yet). The upstream commit is 3ba733f879c2a88910744647e41edeefbc0d92b2 |

Which kernel (uname -r). Ubuntu 20.04 runs from 5.4 to 5.15 kernels. |

Apologies, it looks like it is only in the bionic / 18.04 stream so far, and only in the 5.4-hwe kernel:
That would be 5.4-5.4.0-126.142~18.04.1
It is also in master-next for 18.04 (4.15.0-194.205)
So it seems like I'm premature in opening this issue for 20.04. I imagine this change won't make it there until a future round of patches. Up to you what you want to do with this issue in the meantime. |

Actually, I did find it in Ubuntu 20.04 as well. Here is the commit:
That is in 5.4.0-128.144 |

I looked back and it seems like the 5.4.0-126.142 Ubuntu kernel is the first that I can find to have the commit in the Ubuntu 20.04 series (assuming I'm looking at this properly): |
