Public bug reported:
[ Impact ]
* hwe kernels keep on changing
* jammy zfs-linux 2.1.5 upstream releases + cherry-picks is quite old, thus a
jump to 2.1.12
or 2.2 has potential to break userspace
* Instead cherry-pick patches that continue to enable building zfs-dkms
against hwe kernels, if
one desires to use dkms from the archive, rather than prebuilt modules that all
of Ubuntu kernels ship.
* the cherry-picks area gainst config/* code (autoconf/m4) and kernel
code (module/ & include/), without any changes to userspace tooling or
fixes.
[ Test Plan ]
* verify zfs-dkms module builds from source against v5.15, v5.19, v6.2, v6.3
kernels on jammy
* verify existing zsys installs continue to work
* verify kernel team zfs tests-suites continue to work with v5.15 kernel
[ Where problems could occur ]
* majority of diff is in config macros to detect different compatible
kernel APIs and ABIs and use an appropriate one. there are changes to
uidmap handling for v6.3 kernels, however it is mostly ignored by
userspace without intruducing new feature. LXD will need to be double
checked, as it may assume this driver version seems to accept uidmap
mount options - which it then ignores.
* Note this is still at feature parity with Lunar's upload
2.1.9-2ubuntu1.1, despite having partial kernel driver only build compat
with v6.3 - as v6.3 kernels are not expected to land in lunar, and will
not land in jammy until after mantic release. Mantic already has much
newer 2.2.x series zfs-linux.
[ Other Info ]
* This is similar to previous zfs-linux SRUs we have performed in the
past.
