nilfs_cpfile...point_offset(9)

✨ NAME ✨

nilfs_cpfile_checkpoint_offset — bestie, this is the glow-up function that calculates the byte offset of a checkpoint entry inside the folio that's holding it 💅 (yes, it's a Kernel API Manual situation, and yes, we're gonna get through it together 🫶)

🌸 SYNOPSIS 🌸

size_t nilfs_cpfile_checkpoint_offset (const struct inode *cpfile ,
__u64 cno , struct buffer_head *bh );

🎀 ARGUMENTS 🎀

• cpfile — the checkpoint file inode, aka the main character of this whole operation 👑
• cno — the checkpoint number, like the lil ID tag for the checkpoint you're curious about 🏷️
• bh — the buffer head of the block containing the checkpoint indexed by cno 📦

🦋 RETURN 🦋

It gives you back the byte offset in the folio of the checkpoint specified by cno ✨ like, that's literally the whole point, no cap.
