 #### Tests and Benchmarks
-* Every pull request is tested using a GitHub Actions workflow on multiple platforms by running the [zfs-tests.sh and zloop.sh](
+* Every pull request will by tested by the buildbot on multiple platforms by running the [zfs-tests.sh and zloop.sh](
 https://openzfs.github.io/openzfs-docs/Developer%20Resources/Building%20ZFS.html#running-zloop-sh-and-zfs-tests-sh) test suites.
-`.github/workflows/scripts/generate-ci-type.py` is used to determine whether the pull request is nonbehavior, i.e., not introducing behavior changes of any code, configuration or tests. If so, the CI will run on fewer platforms and only essential sanity tests will run. You can always override this by adding `ZFS-CI-Type` line to your commit message:
-  * If your last commit (or `HEAD` in git terms) contains a line `ZFS-CI-Type: quick`, quick mode is forced regardless of what files are changed.
-  * Otherwise, if any commit in a PR contains a line `ZFS-CI-Type: full`, full mode is forced.
 * To verify your changes conform to the [style guidelines](
 https://github.com/openzfs/zfs/blob/master/.github/CONTRIBUTING.md#style-guides
 ), please run `make checkstyle` and resolve any warnings.
-* Code analysis is performed by [CodeQL](https://codeql.github.com/) for each pull request.
+* Static code analysis of each pull request is performed by the buildbot; run `make lint` to check your changes.
-* Test cases should be provided when appropriate.  This includes making sure new features have adequate code coverage.

+This includes making sure new features have adequate code coverage.

-* The pull request must pass all CI checks before being accepted.
+* The pull request must pass all required [ZFS
+Buildbot](http://build.zfsonlinux.org/) builders before

+issue](https://github.com/openzfs/zfs/issues?q=is%3Aissue+is%3Aopen+label%3A%22Type%3A+Test+Suite%22).
+There are also various [buildbot options](https://openzfs.github.io/openzfs-docs/Developer%20Resources/Buildbot%20Options.html)

-#              will do a DKMS and KMOD test install from both the regular and
-#              testing repos.  On Fedora, it will do a DKMS install from the

-# This file maps the name+email seen in a commit back to a canonical

-# If there is a commit in the history with a "wrong" name or email, list it

-#
-# 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

-#
-# 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.

-# Turn off disk's enclosure slot if an I/O is hung triggering the deadman.
-#
-# It's possible for outstanding I/O to a misbehaving SCSI disk to neither
-# promptly complete or return an error.  This can occur due to retry and
-# recovery actions taken by the SCSI layer, driver, or disk.  When it occurs
-# the pool will be unresponsive even though there may be sufficient redundancy
-# configured to proceeded without this single disk.
-#
-# When a hung I/O is detected by the kmods it will be posted as a deadman
-# event.  By default an I/O is considered to be hung after 5 minutes.  This
-# value can be changed with the zfs_deadman_ziotime_ms module parameter.
-# If ZED_POWER_OFF_ENCLOSURE_SLOT_ON_DEADMAN is set the disk's enclosure
-# slot will be powered off causing the outstanding I/O to fail.  The ZED
-# will then handle this like a normal disk failure and FAULT the vdev.
-#
-# We assume the user will be responsible for turning the slot back on
-# after replacing the disk.
-#
-# Note that this script requires that your enclosure be supported by the
