💖 nilfs_ifile_count_free_inodes 💖

okay bestie, welcome to the nilfs_ifile..._free_inodes(9) page from the Kernel API Manual 🌸 this one is short and sweet, and it’s all about counting free inodes. no cap, the function name is a whole mouthful, but the vibe is basically “tell me the max and tell me how many are free.”

✨ NAME ✨

nilfs_ifile_count_free_inodes — calculate free inodes count 💅

🌈 SYNOPSIS 🌈

int nilfs_ifile_count_free_inodes (struct inode *ifile , u64 *nmaxinodes
, u64 *nfreeinodes );

🎀 ARGUMENTS 🎀

• ifile — ifile inode. yep, that’s the whole note: it’s the ifile inode 🫶
• nmaxinodes — current maximum of available inodes count [out] 📤 this is an output param, so a value gets written back here.
• nfreeinodes — free inodes count [out] 📤 another output param — this is where the free count lands.

🔥 RETURN 🔥

Returns 0 on success, or a negative error code on failure. so: zero = slay ✅, negative = nope 😭. that’s the error-code tea, periodt.
