2# Shown below is a simplified dependency graph of the OpenZFS provided
3# libraries.  Administrative commands (`zfs`, `zpool`, etc) interface with
4# the kernel modules using the `libzfs.so` and `libzfs_core.so` libraries.
5# These libraries provide a stable ABI across OpenZFS point releases.
6#
7# The `libzpool.so` library is a user space build of the DMU and SPA layers
8# used to implement debugging tools (zdb) and code validation tools (ztest).
9# These library interfaces are subject to change at any time.

40# * - A stable ABI is provided for these libraries;
41# when performing an ABI check the following options are applied:
42#
43# --no-unreferenced-symbols: Exclude symbols which are not referenced by
44# any debug information.  Without this _init() and _fini() are incorrectly
45# reported on CentOS7 for libuutil.so.
46#
47# --headers-dir1: Limit ABI checks to public OpenZFS headers, otherwise
48# changes in public system headers are also reported.
49#
50# --suppressions: Honor a suppressions file for each library to provide
51# a mechanism for suppressing harmless warnings.
