A plugin is a .so file that exposes some API to CRIU. Criu loads
plugins from directory pointed by -L option of by CRIU_LIBS_DIR
variable.

When compiling plugin it's enough to put the criu/include/ directory
into headers path.

You can find examples of plugins in these directories:

criu/test/mounts/ext/ -- plugin for external bind mount
test/ext-links/ -- for external network devices
test/unix-callback/ -- for external unix socket
test/zdtm/live/static/criu-rtc.c -- for opened file of unknown type

Thanks,
Pavel
