create_namespace_pmem(9)

✨ NAME ✨

okay so bestie, welcome to create_namespace_pmem(9) from the Kernel API Manual 💖 this one’s whole job is to validate interleave set labelling and retrieve label0 — no cap, that’s the vibe.

🎀 SYNOPSIS 🎀

struct device * create_namespace_pmem (struct nd_region *nd_region ,
       struct nd_mapping *nd_mapping , struct nd_namespace_label *nd_label );

💅 ARGUMENTS 💅

• nd_region — the region with mappings to validate, aka the main character that needs its vibe check.
• nd_mapping — container of dpa-resource-root + labels 🫶
• nd_label — the target pmem namespace label to evaluate, literally the label in question.

🌈 RETURN 🌈

on success you get the created struct device ✨ on error you get ERR_PTR(-errno) 😭 that’s it, that’s the deal.
