# The majority of this code is a fork of upstream repo's in AOSP.
# We are selectively pulling in the pieces of those libs and building
# them into a shared library to use in our system, and to make those
# symbols visible from the lib, we use //common-mk:visibility_default.
# The linter suggests we should explicitly export the symbols we need,
# but in this case we are achieving that by only pulling in the files we
# need, and additionally, upstream will not want to accept us annotating
# all of their code for our fairly specific purpose of build architecture.
# So we disable the linter in this case.
