Fedora 32 updated to kernel 5.8.4-200.fc32.x86_64 dkms build errors: too many arguments to function ‘__vmalloc’

Hi, recently the Fedora 32 updates shipped new kernel version 5.8.4 and the DKMS build procedure for zfs 0.8.4 fails with the following errors:

I see this has already been fixed in #10422
Are there any plans for updated DKMS packages for Fedora 32 ?

@plevart: https://openzfs.github.io/openzfs-docs/Getting%20Started/Fedora.html
You will have to rever to 5.7.x and just wait. There is no specific date and OpenZFS does not follow the kernel release schedule to sync with it (unfortunately).

@plevart please close this issue, this “bug” has already been resolved in latest RC1 release.
