I have a geom that sometimes (very rarely) needs to modify the data in an u= nmapped BIO. Completely removing unmapped support from the entire geom is o= verkill. What is the best way of converting a single unmapped BIO to a mapp= ed address so I can access the data? Basically I want g_io_transient_map_bio(), but that function is static. Dup= licating that code in my geom is not elegant.
