gfs2_write_jdata_folio(9)

💖 NAME 💖

okay so bestie, this is the gfs2_write_jdata_folio(9) page from the Kernel API Manual, and the name is literally this:

gfs2_write_jdata_folio — the gfs2 jdata-specific version of block_write_full_folio 💅

---

✨ SYNOPSIS ✨

int gfs2_write_jdata_folio (struct folio *folio , struct
       writeback_control *wbc );

---

🎀 ARGUMENTS 🎀

• folio — the folio to write. That's the main character here 🫶
• wbc — the writeback control. The vibe manager for the writeback, basically ✨

---

🦋 DESCRIPTION 🦋

So lowkey this is the same as calling block_write_full_folio, but plot twist: it also writes pages outside of i_size 😭🔥

That's the whole flex. Same call energy, plus pages outside i_size get written too. No cap.
