💖 nvdimm_init_nsarea(9) 💖

okay so bestie, welcome to the nvdimm_init_nsarea(9) page — it lives in the Kernel API Manual, and it's honestly giving "small function, big responsibilities" ✨

🌸 NAME 🌸

nvdimm_init_nsarea — the glow-up routine that figures out the geometry of a dimm's namespace area 🎀

✨ SYNOPSIS ✨

int nvdimm_init_nsarea (struct nvdimm_drvdata *ndd );

🦋 ARGUMENTS 🦋

• ndd — the dimm to initialize, like, the actual main character here 👑

🔥 RETURN 🔥

• 0 — the area is already valid, we love a queen who's already ready 💅
• -errno — on error 😭

💜 SEE ALSO 💜

• Kernel file ./drivers/nvdimm/dimm_devs.c
• nd_pmem_max_contiguous_dpa(9)
• nd_pmem_available_dpa(9)
• nvdimm_allocated_dpa(9)

ngl, the return value is literally the whole story here — 0 means "already valid", anything else is -errno and you should go check what went wrong, no cap 🫶

and that's the whole vibe check, bestie — this one's from ./drivers/nvdimm, dated October 2026, in the Kernel API Manual ✨ mwah, go read the SEE ALSO list, ily 💖🌈
