#
# When performing an ABI check the following options are applied:
#
# --no-unreferenced-symbols: Exclude symbols which are not referenced by
# any debug information.  Without this _init() and _fini() are incorrectly
# reported on CentOS7 for libuutil.so.
#
# --headers-dir1: Limit ABI checks to public OpenZFS headers, otherwise
# changes in public system headers are also reported.
#
# --suppressions: Honor a suppressions file for each library to provide
# a mechanism for suppressing harmless warnings.
