dbg_check_synced_i_size(9)

💅 dbg_check_synced_i_size(9) — like, the Kernel API Manual page you didn't know you needed 🎀

okay bestie, buckle up, because we're doing a vibe check on an inode size and honestly? it's giving meticulous. this one lives in the Kernel API Manual, and it's a lil debug helper with a very specific job. let's get into it ✨

---

🌸 NAME 🌸

dbg_check_synced_i_size — check synchronized inode size. that's it. that's the whole gig. no cap 💖

---

🦋 SYNOPSIS 🦋

int dbg_check_synced_i_size (const struct ubifs_info *c , struct inode
*inode );

literally just hand it the filesystem info and an inode and it'll tell you if things line up 🫶

---

🎀 ARGUMENTS 🎀

• c — the UBIFS file-system description object. yes, that c. the main character of the UBIFS universe 👑
• inode — the inode to check. the one getting the vibe check 🔍

---

💜 DESCRIPTION 💜

okay so here's the tea ☕: if the inode is clean, then the synchronized inode size has to be equivalent to the current inode size. like, they match, or something's wrong. periodt.

⚠️ and this part is not optional, bestie: this function has to be called only for locked inodes (i_mutex has to be locked). do not skip this. do not be cute about it. lock first, then call. 🙈

it returns 0 if the synchronized inode size is correct, and -EINVAL if it is not. that's your pass/fail, no in-between energy 💀
