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

# These nine libraries are intermediary build components.
#
# * - A stable ABI is provided for these libraries;
# 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.
