Bug 702144 – sys-fs/zfs-kmod-0.8.2 should set ZFS_KERNEL_COMPAT="5.4"

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description cyshei 2019-12-06 07:42:01 UTC]

According to https://github.com/zfsonlinux/zfs/releases/tag/zfs-0.8.2, it is compatible with kernels up to 5.4, but emerge on a 5.4 kernel currently errors out because ZFS_KERNEL_COMPAT is set to 5.3.

I confirmed that changing this to 5.4 in a local overlay compiles successfully against a 5.4 kernel.

Reproducible: Always

I usually refer to this file to determine compatibility

https://github.com/zfsonlinux/zfs/blob/zfs-0.8.2/META

and it says 5.3


but yeah I see commit message says compatible up to 5.4

I'll need to investigate it a bit before bumping compat. There've been nasty bugs related to bumping compat in the past.

also, ebuild contains a magic variable: ZFS_KERNEL_COMPAT_OVERRIDE 


you can use the following command

ZFS_KERNEL_COMPAT_OVERRIDE=5.4 emerge zfs-kmod

no need to copy ebuild to local overlay.

I just found Brian's comment here, which explains why the META says 5.3 while the release notes say 5.4: https://github.com/zfsonlinux/zfs/pull/9654#issuecomment-560537636

thanks for finding confirmation!

rebvumped ebuild so everyone who have 5.4 kernel masked see the bump and unmask it.
