# NAME:
|
|
# divergence.sh - find divergences between Linux and ACPICA
|
|
#
|
|
# SYNOPSIS:
|
|
# divergence.sh [-s] <path>
|
|
#
|
|
# DESCRIPTION:
|
|
# Find the divergences between these sets of source code:
|
|
# 1) The current ACPICA source from the ACPICA git tree
|
|
# 2) The version of ACPICA that is integrated into Linux
|
|
# The goal is to eliminate as many differences as possible between
|
|
# these two sets of code.
|
|
# Parameters:
|
|
# path Path of directory to the Linux source tree.
|
|
# Options:
|
|
# -s Single direction
|
|
# (indent on Linux rather than both of Linux and ACPICA)
|
|
#
