Bug#929557: linux: restore __kernel_fpu needed for zfs for AES-NI/AVX support [mainline not in debian yet]
Source: linux
Severity: wishlist
Tags: upstream patch
Dear Maintainer,
GKH has been purging __kernel_fpu_{begin,end}() from all kernels
including LTS (4.19/5) and it's needed for AES-NI/AVX support in the zfs
package. If this commit makes it to debian it will break all older zfs
releases and will cause very high cpu and terrible speed with encrypted
zfs pools. Arch Linux has already reverted the offending commit in their
distro. Patch available at
https://raw.githubusercontent.com/Mic92/nixpkgs/7b77c27caa8617c82df5c5af6b9ce6ae010d7f9a/pkgs/os-specific/linux/kernel/export_kernel_fpu_functions.patch
Thank you!
