✨ NAME ✨

gfs2_release_folio — free the metadata associated with a folio

like literally, it's the cleanup queen 👑

---

🎀 SYNOPSIS 🎀

bool gfs2_release_folio (struct folio *folio , gfp_t gfp_mask );

that's the whole vibe. two args, returns a bool, slays ✨

---

🦋 ARGUMENTS 🦋

• folio — the folio that's being released. this is the main character of the whole function, no cap 🫶
• gfp_mask — passed from Linux VFS, ignored by us. yeah she's just here for the vibes, we literally do not look at her 🙈

---

💖 DESCRIPTION 💖

so what does she actually do? Calls try_to_free_buffers to free the buffers and put the folio if the buffers can be released. that's it, that's the whole flex 💅

lowkey iconic of her to delegate the actual work and still take the credit. main character energy fr fr 🔥
