arch_kexec_..._image_probe(9)

💅 NAME

ok so arch_kexec_kernel_image_probe — bestie, this one does the additional handling needed to setup kexec segments. that's the whole vibe. it's the lil extra love the arch layer gives you before stuff gets loaded. ✨

(it lives in the Kernel API Manual, which is giving very official, very "i have a job" energy 🎀)

---

🌸 SYNOPSIS

int arch_kexec_kernel_image_probe (struct kimage *image , void *buf ,
       unsigned long buf_len );

look at her. three args, one int return, zero drama. slay. 💅

---

🫶 ARGUMENTS

• image — the kexec image that's currently being loaded. main character, obviously. 👑
• buf — a buffer that points at elf data. yes, that elf data. 🧚
• buf_len — how long buf is. the length. the size. the measure of things. 📏

---

✨ DESCRIPTION

returns 0 on success, and a negative errno on error. that's literally it. no cap. one line of contract, zero games. 🔥

fr fr bestie, 0 = we good, negative = something went sideways. don't forget it. 💀
