.SH "DESCRIPTION"
Builds an exclusion entry matching every controller of a subsystem (the
entry constrains only the NQN) inside libnvme -- the caller needs no
knowledge of the on-disk entry format -- then appends it via
\fBlibnvmf_exclusion_add\fP.  Creates the list if it does not exist.
.SH "RETURN"
0 on success, -EINVAL if \fIctx\fP or \fIsubsysnqn\fP is NULL/empty,
negative errno otherwise.
