key_max_inode_size(9) 🎀

okay so bestie, welcome to the Kernel API Manual — this page is all about key_max_inode_size, and it is literally here to get the maximum file size allowed by the current key format. no cap, that’s the whole vibe. 💅✨

✨ NAME ✨

key_max_inode_size — get maximum file size allowed by current key format. 💖

🌸 SYNOPSIS 🌸

unsigned long long key_max_inode_size (const struct ubifs_info *c );

the way this signature is giving “i return an unsigned long long and i take a const struct ubifs_info * named c” 😭✨

💅 ARGUMENTS 💅

• c — the UBIFS file-system description object. this is the one and only argument, bestie 🫶
