okay bestie so this is a page from the Kernel API Manual — yes, the kernel has its own manual, and yes, we're reading it for fun now 💅

🎀 NAME 🎀

gfs2_jdata_writepages — write a bunch of dirty pages back to disk 💾✨

Like, a bunch. Plural. We're not out here doing one page at a time, that's not the vibe.

🌸 SYNOPSIS 🌸

int gfs2_jdata_writepages (struct address_space *mapping , struct
writeback_control *wbc );

She takes two pointers and returns an int, no cap. 🫶

---

🦋 ARGUMENTS 🦋

• mapping — the mapping to write. this is the thing you're flushing, bestie — struct address_space energy.
• wbc — the writeback control. the little control panel that tells the whole operation how to behave 🎛️
