search_inode(9)

💅 search_inode(9) — like, the inode-speedrun page

okay bestie, welcome to the search_inode manual page, part of the Kernel API Manual collection ✨ this one's short and sweet and honestly kind of iconic for how specific it is 🎀

---

🌸 NAME 🌸

search_inode — literally the function that goes looking for an inode inside the RB-tree of inodes 🔍🦋

---

✨ SYNOPSIS ✨

struct fsck_inode * search_inode (struct fsck_data *fsckd , ino_t inum );

that's the whole signature, no cap 💅

---

🫶 ARGUMENTS 🫶

• fsckd — the FS checking information 🧚 this is your data pass-around buddy
• inum — the inode number you're trying to find 👑 the actual target of the search

---

💖 DESCRIPTION 💖

so this is a helper function for 'check_leaf' 🍓 what it does is it searches for the inode inum in the RB-tree of inodes, and then it hands you back an inode information pointer 🌈

and if the inode isn't in there? you get NULL. that's it, that's the whole vibe 😭 not found, no inode, no problem (well, some problem, but a returned problem) 💀

one thing though bestie — remember this page is filed under ./fs/ubifs, dated October 2026 🌸 so if you're quoting it in the group chat, that's the receipt 💜

okay that's the page, ily, go find those inodes 🧚✨💅
