add_kernel_mem_range(9)

✨ add_kernel_mem_range(9) ✨

okay bestie, welcome to the Kernel API Manual — this one's a little function from the PowerPC kexec corner of the kernel and honestly it's giving "small but essential" 🎀

---

💖 NAME 💖

add_kernel_mem_range — literally just adds the kernel text region to whatever memory ranges list you hand it 🫶

---

🌸 SYNOPSIS 🌸

int add_kernel_mem_range (struct crash_mem **mem_ranges );

---

🦋 ARGUMENTS 🦋

• mem_ranges — the range list you want the memory range added to. that's it, that's the whole vibe ✨

---

🧚 DESCRIPTION 🧚

so like, the whole personality of this function is its return value, no cap: it returns 0 on success, and a negative errno on error 😭 that's the documented behaviour, and we are not adding lore that isn't there.
