nilfs_sufil...usage_offset(9)

💅 nilfs_sufil...usage_offset(9) — the Kernel API Manual, girlies ✨

okay so picture this: you're deep in the Kernel API Manual, section 9, and the page you've pulled up is literally called nilfs_sufil...usage_offset(9) (yeah the name's a little truncated, we don't gatekeep, we love her anyway 🫶). This is the one that tells you where a segment usage entry lives inside its folio. main character energy, honestly.

---

✨ NAME ✨

nilfs_sufile_segment_usage_offset — bestie, this one calculates the byte offset of a segment usage entry inside the folio that contains it. that's the whole vibe. 💖

---

🌸 SYNOPSIS 🌸

size_t nilfs_sufile_segment_usage_offset (const struct inode *sufile ,
__u64 segnum , struct buffer_head *bh );

like, yes, the line wraps weird in the synopsis, that's just how she is, don't come for her 😭

---

🎀 ARGUMENTS 🎀

• sufile — the segment usage file inode. the main inode of the whole operation, no cap 👑
• segnum — the number of the segment usage. which entry are we talking about, queen? 🔥
• bh — the buffer head of the block containing the segment usage indexed by segnum. it's literally the block holder for that entry, okurrr 💅

---

⭐ RETURN ⭐

She gives you back the byte offset in the folio of the segment usage entry. that's it, that's the gift 🎁✨
