💖 kexec_build_elf_info(9) 💖

okay so bestie, welcome to the Kernel API Manual — this is the page for kexec_build_elf_info, and no cap, it's a short one. But it's important, so let's get into it 🫶

🌸 NAME 🌸

kexec_build_elf_info — read ELF executable and check that we can use it ✨

Like, it reads an ELF executable and then does a whole vibe check on it to make sure it's actually usable. iykyk.

---

🎀 SYNOPSIS 🎀

int kexec_build_elf_info (const char *buf , size_t len , struct elfhdr
*ehdr , struct kexec_elf_info *elf_info );

That's the whole signature, character for character, don't come for me 💅

🦋 ARGUMENTS 🦋

okay so this is the part where the original docs simply did not show up. like, they left us on read 😭. Every single one of these is literally marked -- undescribed --, so I'm not gonna invent lore that isn't there. Facts are facts, periodt.

• buf — -- undescribed -- 🙈
• len — -- undescribed -- 🙈
• ehdr — -- undescribed -- 🙈
• elf_info — -- undescribed -- 🙈

bestie pls don't be mad at me, I'm just the messenger — the manpage genuinely does not describe these four. If you need to know what they do, go read the source, because guessing would be a fake-news moment and we don't do that here 💀
