A Kernel split changes committing script (used for splitting massive OEM kernel commits)

kernel-rebase.sh

#!/usr/bin/bash

# author: Vaisakh Murali <mvaisakh@statixos.com>

#
# Before you start, make sure you squash all split OEM commits into
# one single commit. This will break down the single huge commit
# into multiple smaller commits, helping to cleanup OEM codes easier.
#
# Make sure this script is renamed to rebase.sh as the script
# explicitly removes rebase.sh from being committed during the split
# process.

# Split OEM Changes
echo "Split OEM modifications"

echo "Initial reset"
git reset HEAD^ . >/dev/null 2>&1
echo "Committing a starting point commit (This commit might be authored by the original OEM author)"
git commit -sm "BEGIN OEM Imports" --allow-empty --amend >/dev/null 2>&1

echo "Splitting commits... (This might take a while, do not interrupt)"
