💖 libnvme — enum nvme_fid_supported_effects 💖

okay bestie, sit DOWN because we're doing the libnvme API manual, and this page is specifically about enum nvme_fid_supported_effects — the FID Supported and Effects Data Structure definitions. it's giving "little enum, huge responsibilities" and honestly? obsessed. 🎀

this whole thing lives under the libnvme API manual, section 2, so like — API-adjacent, C-flavored, very much for the girlies writing NVMe code at 3am. ✨

not me listing all fifteen like a devoted stan. the way that "change" shows up in four different flavors (UDCC, NCC, NIC, CCC) and the way "Scope" shows up in six… it's a whole theme, bestie. 🌈

that's the entire page, no crumbs left behind. if you needed the full enumeration, you got the full enumeration. periodt. 💜

sign-off time 🫶 this lil' cutie pie came out of the libnvme API Manual, dated July 2026, and yes — it's still riding under the libnvme(2) banner like the icon it is. go forth and enumerate responsibly, bestie. 💖✨🎀
