-1) build zfs modules for Ubuntu 20.04 and 22.04 (~15m)
-2) 2x zloop test (~10m) + 2x sanity test (~25m)
-3) 4x functional testings in parts 1..4 (each ~1h)
-4) cleanup and create summary
-   - content of summary depends on the results of the steps
-
-When everything runs fine, the full run should be done in
-about 2 hours.

-The codeql.yml and checkstyle.yml are not part in this circle.

-# This file maps the name+email seen in a commit back to a canonical
-# name+email. Git will replace the commit name/email with the canonical version
-# wherever it sees it.
-#
-# If there is a commit in the history with a "wrong" name or email, list it
-# here. If you regularly commit with an alternate name or email address and
-# would like to ensure that you are always listed consistently in the repo, add
-# mapping here.
-#
-# On the other hand, if you use multiple names or email addresses legitimately
-# (eg you use a company email address for your paid OpenZFS work, and a
-# personal address for your evening side projects), then don't map one to the
-# other here.
-#
-# The most common formats are:
-#
-# Canonical Name <canonical-email>
-# Canonical Name <canonical-email> <commit-email>
-# Canonical Name <canonical-email> Commit Name <commit-email>
-#
-# See https://git-scm.com/docs/gitmailmap for more info.
-
-# These maps are making names consistent where they have varied but the email
-# address has never changed. In most cases, the full name is in the
-# Signed-off-by of a commit with a matching author.

-OpenZFS uses the MAJOR.MINOR.PATCH versioning scheme described here:
-
-  * MAJOR - Incremented at the discretion of the OpenZFS developers to indicate
-    a particularly noteworthy feature or change. An increase in MAJOR number
-    does not indicate any incompatible on-disk format change. The ability
-    to import a ZFS pool is controlled by the feature flags enabled on the
-    pool and the feature flags supported by the installed OpenZFS version.
-    Increasing the MAJOR version is expected to be an infrequent occurrence.
-
-  * MINOR - Incremented to indicate new functionality such as a new feature
-    flag, pool/dataset property, zfs/zpool sub-command, new user/kernel
-    interface, etc. MINOR releases may introduce incompatible changes to the
-    user space library APIs (libzfs.so). Existing user/kernel interfaces are
-    considered to be stable to maximize compatibility between OpenZFS releases.
-    Additions to the user/kernel interface are backwards compatible.
-
-  * PATCH - Incremented when applying documentation updates, important bug
-    fixes, minor performance improvements, and kernel compatibility patches.
-    The user space library APIs and user/kernel interface are considered to
-    be stable. PATCH releases for a MAJOR.MINOR are published as needed.
-
-Two release branches are maintained for OpenZFS, they are:
-
-  * OpenZFS LTS - A designated MAJOR.MINOR release with periodic PATCH
-    releases that incorporate important changes backported from newer OpenZFS
-    releases. This branch is intended for use in environments using an
-    LTS, enterprise, or similarly managed kernel (RHEL, Ubuntu LTS, Debian).
-    Minor changes to support these distribution kernels will be applied as
-    needed. New kernel versions released after the OpenZFS LTS release are
-    not supported. LTS releases will receive patches for at least 2 years.
-    The current LTS release is OpenZFS 2.1.
-
-  * OpenZFS current - Tracks the newest MAJOR.MINOR release. This branch
-    includes support for the latest OpenZFS features and recently releases
-    kernels.  When a new MINOR release is tagged the previous MINOR release
-    will no longer be maintained (unless it is an LTS release). New MINOR
-    releases are planned to occur roughly annually.
