foreach_descriptor(9)

💖 NAME 💖

foreach_descriptor — go through the active part of the log ✨

okay bestie, this page is foreach_descriptor(9) from the Kernel API Manual, and it's lowkey iconic for doing exactly what the name says: getting you through the active part of the log. 🫶

✨ SYNOPSIS ✨

int foreach_descriptor (struct gfs2_jdesc *jd , u32 start , unsigned int
end , int pass );

---

🎀 ARGUMENTS 🎀

• jd — the journal 💖
• start — the first log header in the active region ✨
• end — the last log header — and bestie, don't process the contents of this entry (the original page is literally serving double )) energy, so respect the boundary) 🙈
• pass — iteration number (foreach_descriptor is called in a for loop) 🔁

---

🦋 DESCRIPTION 🦋

The whole assignment: call a given function once for every log descriptor in the active portion of the log. That's it, that's the main character move. 💅
