Public bug reported:
Due to a mistake in the BUILD_EXCLUSIVE_KERNEL regex in dkms.conf, dkms
will still consider zfs-dkms to be buildable on kernel version 5.10+.
This can happen if one installs a mainline kernel from the mainline PPA
for one reason or another [1].
The following patch to dkms.conf should fix the issue:
--- ./dkms.conf.orig 2021-03-16 04:15:55.077568974 +0700
+++ /usr/src/zfs-0.8.3/dkms.conf 2021-03-16 04:17:16.598219797 +0700

Although it's not convenient for me at the moment to create a debdiff.
Related: LP: #1902701
[1] For me it's to get a complete fix for LP: #1887190, as Focal's HWE
kernel doesn't seem to work.
