proc_ulong_u2k_conv_uop(9) 💅

hiii bestie, welcome to the Kernel API Manual — this is the page for proc_ulong_u2k_conv_uop(9), and it's literally the little helper that assigns a user value to a kernel pointer. let's get into it ✨

---

🌸 NAME 🌸

proc_ulong_u2k_conv_uop — assign user value to a kernel pointer 💫

---

✨ SYNOPSIS ✨

int proc_ulong_u2k_conv_uop (const ulong *u_ptr , ulong *k_ptr , ulong
       (*u_ptr_op)(const ulong) );

---

🫶 ARGUMENTS 🫶

• u_ptr — pointer to user space variable 👀
• k_ptr — pointer to kernel variable 🧠
• u_ptr_op — execute this function before assigning to k_ptr 🎬

---

💖 DESCRIPTION 💖

okay so here's the vibe: this one uses WRITE_ONCE to assign the value to k_ptr. if u_ptr_op is not NULL, it executes u_ptr_op, bestie. that's the whole moment. 🦋

---

🌈 RETURN 🌈

• 0 on success. slay. ✅
