💫 gfs2_end_log_write(9) 💫

okay so bestie, welcome to the gfs2_end_log_write(9) page — it lives in the Kernel API Manual and it's literally all about wrapping up i/o to the log. yes, that log. the gfs2 one. we're in the kernel, we're doing kernel things, and it's giving very much "last one out turns off the lights" energy. 🎀

✨ NAME ✨

gfs2_end_log_write — end of i/o to the log 🫶

---

🌸 SYNOPSIS 🌸

void gfs2_end_log_write (struct bio *bio );

---

🦋 ARGUMENTS 🦋

• bio — The bio 💅 (yes bestie, that's the whole description, it's short and iconic and we respect it)

---

🌈 DESCRIPTION 🌈

okay so here's the vibe: each bio_vec contains either data from the pagecache or data relating to the log itself. two kinds of data, one array, no cap. 🧚

so what we do here is iterate over the bio_vec array and process both kinds of data. that's it, that's the function, and honestly? she ate. 🔥
