💖 NAME 💖

okay so bestie, meet xa_mk_value(9) from the Kernel API Manual — the function that creates an XArray entry from an integer. That's literally the whole plot. ✨

✨ SYNOPSIS ✨

void * xa_mk_value (unsigned long v );

🎀 ARGUMENTS 🎀

• v — the value to store in XArray. One argument, one job, no cap.

🌈 CONTEXT 🌈

Any context. Like, any context — that's the vibe check the page gives. 🦋

🦋 RETURN 🦋

An entry suitable for storing in the XArray. So you get back a thing that's ready to live in the XArray, periodt. 👑
