gfs2_writepages(9)

✨ gfs2_writepages ✨

okay so real talk, this is a page straight out of the Kernel API Manual, and it's about gfs2_writepages — the function that grabs a whole pile of dirty pages and yeets them back to disk 🦋 bestie, it's giving "cleanup crew but make it filesystem" energy and honestly? obsessed.

🌸 SYNOPSIS 🌸

int gfs2_writepages (struct address_space *mapping , struct
writeback_control *wbc );

like, that's the whole signature, no cap. two pointers in, one int out 💅

🎀 ARGUMENTS 🎀

• mapping — the mapping you wanna write, periodt. this is the mapping to write, that's literally the whole vibe. 🗺️
• wbc — the write-back control, aka the little control object that rides along and tells the write-back what's up. 🎛️

---

💖 DESCRIPTION 💖

so here's the tea: it's used for both ordered and writeback modes. that's it, that's the description, and honestly she's iconic for being that concise. two modes, one function, main character energy fr fr 👑
