The release notes (https://github.com/openzfs/zfs/releases/tag/zfs-0.8.4) states that the code has some changes for Linux 5.7 as well although the kernel compatibility is 2.6.32-5.6. My Gentoo system here now runs under Linux 5.7.2 and sys-fs/zfs-kmod-0.8.4 (I just changed the latest supported kernel version) no issues.
ebuild set's what is set in META file for release https://github.com/openzfs/zfs/blob/6b18d7df3772cffa6469b00866d7eae585b912ae/META on rare occasions we can disregard it, but it's the source of truth for ebuild on release. @ryao might provide more insight, I think he wanted to test compat and bump it if everything is ok, but it has not happened yet. BTW: not sure if you use it, we provide special magical variable for zfs-kmod package if you for example export ZFS_KERNEL_COMPAT_OVERRIDE=5.7 and emerge it, you don't have to edit the ebuild by hand. to save it permanently, you have to do something like this: > mkdir -p /etc/portage/env/sys-fs > echo 'export ZFS_KERNEL_COMPAT_OVERRIDE=5.7' >> /etc/portage/env/sys-fs/zfs-kmod-0.8.4' of course it voids the warranty =)
No I was not using it. Suggestion: put an elog at this subject?
I have this issue with 5.8 kernel - should it support it?
no. but you can use 9999 ebuild if you really want linux-5.8
@ryao: any ideas when a version with support for 5.8 be released? I get this error with 5.8.3: /var/tmp/portage/sys-fs/zfs-kmod-0.8.4-r1/work/zfs-0.8.4/module/spl/spl-kmem.c: In function 'spl_kmem_alloc_impl': /var/tmp/portage/sys-fs/zfs-kmod-0.8.4-r1/work/zfs-0.8.4/module/spl/spl-kmem.c:183:11: error: too many arguments to function '__vmalloc' 183 | ptr = __vmalloc(size, lflags | __GFP_HIGHMEM, | ^~~~~~~~~ In file included from /var/tmp/portage/sys-fs/zfs-kmod-0.8.4-r1/work/zfs-0.8.4/include/spl/sys/vmem.h:30, from /var/tmp/portage/sys-fs/zfs-kmod-0.8.4-r1/work/zfs-0.8.4/module/spl/spl-kmem.c:28: ./include/linux/vmalloc.h:111:14: note: declared here 111 | extern void *__vmalloc(unsigned long size, gfp_t gfp_mask); | ^~~~~~~~~ make[5]: *** [scripts/Makefile.build:281: /var/tmp/portage/sys-fs/zfs-kmod-0.8.4-r1/work/zfs-0.8.4/module/spl/spl-kmem.o] Error 1
The vmalloc issue had been spotted and the code has been merged on Jun 8th, 2020, see =>`https://github.com/openzfs/zfs/pull/10422 Also another issue has been reported for Linux 5.8.x : https://github.com/openzfs/zfs/issues/10533
if you want to try - you can use this patch https://aur.archlinux.org/cgit/aur.git/plain/linux-5.8-compat-__vmalloc.patch?h=zfs-linux place it to: > /etc/portage/patches/sys-fs/zfs-kmod-0.8.4-r1/linux-5.8-compat-__vmalloc.patch also you'll need to define post_src_prepare() function for ebuild which runs eautoreconf. for example > mkdir /etc/portage/env/sys-fs > echo 'export ZFS_KERNEL_COMPAT_OVERRIDE=5.8' > /etc/portage/env/sys-fs/zfs-kmod-0.8.4-r1 > echo 'post_src_prepare() { eautoreconf ; }' >> /etc/portage/env/sys-fs/zfs-kmod-0.8.4-r1 after that > emerge --oneshot =sys-fs/zfs-kmod-0.8.4-r1 probably will produce a working build =) but all warranty is void. make backups. or just wait a bit, 0.8.5 should be out soon-ish.

2.0.0-rc1 available as well (experimental, please make backups) and is compatible with 5.8 kernels.
zfs-0.8.5 just landed, it should be compatible with 5.8 kernels and probably 5.9 as well, once it's out, but for now ebuild enforces 5.8, subject to change. I'm closing this, will try to stabilize 0.8.5 sooner than 30 days, it's mostly bugfix/compat release anyway.
