# Script to query patchwork to see if a list of patches on applied to a tree
# were posted upstream or not
#  - By Amit Kucheria

# Assumption:
#  Run in the kernel source git tree on the release branch
#  pwclient (from patchwork sources) is installed and available in PATH

# Script is meant to be run on RPK.
# Input:
#  <rpk release version>
#  <vanilla kernel version>
#
# Output:
#  file containing SHA, Author and Subject of patches
