Hello,

I have been trying to build a zfs module for the linux-edge kernel. I have
hardware that is not supported by linux-lts. I get the following error:
make[5]: *** No rule to make target
'/home/user/abuild/aports/main
/zfs-edge/src/zfs-2.2.6/6.11.0-0-edge/
module/os/linux/spl/spl-atomic.o', needed by '/home/user/abuild/aports/
main/zfs-edge/src/zfs-2.2.6/6.11.0-0-edge/module/spl.o'.  Stop.
zfs-lts does build successfully.

This is the process that I use:
abuild-keygen -a -i
mkdir abuild
cd abuild
git clone https://gitlab.alpinelinux.org/alpine/aports
cd aports/main/linux-headers
vi APKBUILD
  Edit this line:
    pkgver=6.11
abuild clean
abuild deps
abuild fetch
abuild checksum
abuild
doas vi /etc/apk/repositories
  Add this line:
    /home/user/packages/main/
doas apk update
doas apk add linux-headers
cd ../../community/linux-edge
abuild deps
doas rm -rf /lib/modules/firmware/nvidia
doas apk fix
abuild fetch
abuild
cd ../../main
cp -av zfs-lts zfs-edge
cd zfs-edge
vi APKBUILD
  Edit these lines:
    _flavor=${FLAVOR:-edge}
    _kver=6.11.0
  Comment out these lines:
    # for custom kernels set $FLAVOR
    # case $CARCH in
    #     x86|x86_64|aarch64) _extra_flavors="virt";;
    # esac
  Edit this line:
    local _kapkbuild="$startdir"/../../edge/linux-$_flavor-/APKBUILD
abuild deps
abuild fetch
apk list -I > zfs-edge-apk.list
abuild -K 2>&1 | tee zfs-edge-build.log

uname for the running kernel:

installed packages, and lists of files in the src directories to:

Could you try if it works if you add these 2 lines?

The first line is copied from https://github.com/openzfs/zfs/commit/f2f4ada240e3560faa721082c4a62dcb0cce0115

That worked. Thank you!
