💅 nilfs_palloc_entry_offset(9) — like, the kernel API manual one 🎀

okay so bestie, welcome to nilfs_palloc_entry_offset(9), a genuinely iconic little function living in the Kernel API Manual. it does exactly one job and it does it flawlessly: it tells you where in the folio an entry actually sits. no cap. ✨

🌸 NAME 🌸

nilfs_palloc_entry_offset — calculate the byte offset of an entry in the folio containing it 💖

🦋 SYNOPSIS 🦋

size_t nilfs_palloc_entry_offset (const struct inode *inode , __u64 nr ,
const struct buffer_head *bh );

that's the whole signature, copy it exactly pls, she's precise 💅

✨ ARGUMENTS ✨

  • inode — the inode of the metadata file that's using this allocator. yes, that one. 👑
  • nr — the serial number of the entry (like, e.g. the inode number). it's a __u64, she's big. 🔥
  • bh — the buffer head of the entry block. the whole squad is here. 🫶

⭐ RETURN ⭐

returns the byte offset in the folio of the entry nr. that's it, that's the tea. 🍓

💀 reminder bestie: every single one of those is (9) and spelled exactly like that, so don't get creative when you're grepping. 🙈
