Description

In internal.cc

int clone(IoCtx& p_ioctx, const char *p_name, const char *p_snap_name,
IoCtx& c_ioctx, const char *c_name,
uint64_t features, int *c_order,
uint64_t stripe_unit, int stripe_count)

p_imctx->snap_lock.get_read();
    p_features = p_imctx->features;
    size = p_imctx->get_image_size(p_imctx->snap_id);
    p_imctx->is_snap_protected(p_imctx->snap_id, &snap_protected);
    p_imctx->snap_lock.put_read();

Shall check returned value of is_snap_protected() method
