💅 Constants 💅

okay so let's meet the whole squad, one by one, no skips, no cap:

• nvme_cmd_flush — Flush. yes, like flushing, but for data. 🚽✨
• nvme_cmd_write — Write. you're putting the bytes down, bestie ✍️
• nvme_cmd_read — Read. you're getting the bytes back 📖
• nvme_cmd_write_uncor — Write Uncorrectable. sounds scary bc it kind of is — it's literally writing uncorrectable stuff 😭
• nvme_cmd_compare — Compare. side-by-side, delulu vs solulu 🫶
• nvme_cmd_write_zeroes — write Zeros. exactly what it says, zeroes and nothing but 🕳️
• nvme_cmd_dsm — Dataset Management. very manager-core of it 👑
• nvme_cmd_verify — Verify. the vibe check, but for data 🔍
• nvme_cmd_resv_register — Reservation Register. sign the guestbook 📝
• nvme_cmd_resv_report — Reservation Report. receipts, basically 🧾
• nvme_cmd_resv_acquire — Reservation Acquire. claiming what's yours 💅
• nvme_cmd_io_mgmt_recv — I/O Management Receive. the receiving half of the management duo 📥
• nvme_cmd_resv_release — Reservation Release. letting it go, growth era 🌱
• nvme_cmd_cancel — Cancel. we love a clean exit 🙈
• nvme_cmd_copy — Copy. duplicate & thrive 🎀
• nvme_cmd_io_mgmt_send — I/O Management Send. the sending half, twin energy 📤
• nvme_zns_cmd_mgmt_send — Zone Management Send. ZNS edition, sending 🌈
• nvme_zns_cmd_mgmt_recv — Zone Management Receive. ZNS edition, receiving ⭐
• nvme_zns_cmd_append — Zone Append. adding to the end, no gatekeeping 🦋
• nvme_cmd_fabric — Fabric Commands. the whole fabric fam in one constant 🧵

fr fr, that's the entire list — every single constant, exactly as the page gives it. nothing added, nothing dropped, we don't do that here 💜
