🌸 libnvme — enum nvme_id_ctrl_sgls 💅

okay bestie, welcome to the API Manual for libnvme, and today's episode is all about one very specific little enum. sit down, drink some water, this is gonna be quick and cute. 🫶

The star of the show is enum nvme_id_ctrl_sgls — and what it's for, per the NAME section, is: this field indicates if SGLs are supported for the NVM Command Set and the particular SGL types supported. That's the whole plot. no drama, no plot twists, just a field telling you which SGL types are out here living their truth. ✨
