💅 vdo_increment_packer_flush_generation(9) — the Kernel API Manual glow-up ✨

okay so bestie, welcome to the Kernel API Manual entry for vdo_increment_packer_flush_generation fr fr. this is a section 9 (kernel API) page and it's short but she's iconic 🎀

---

✨ NAME ✨

vdo_increment_packer_flush_generation — literally just Increment the flush generation in the packer. that's the whole job. no cap 💅

---

🦋 SYNOPSIS 🦋

void vdo_increment_packer_flush_generation (struct packer *packer );

she returns void (nothing, nada, zero) and takes exactly one thing, so don't come at her with extra arguments bestie 😭

---

🌸 ARGUMENTS 🌸

• packer — The packer. that's it. that's the whole description. she's giving minimalism, she's giving "i trust you already know what a packer is" 🫶

---

🔥 DESCRIPTION 🔥

so here's the tea ☕ — this one bumps the flush generation up in the packer.

and like, it doesn't just increment the number, okay? it also causes the packer to flush, so that any VIOs from previous generations will exit the packer 🚪✨ like a little eviction notice but make it graceful. the old-gen VIOs literally pack their bags and leave. main character energy for the new generation tbh 👑

no cap, the flush is part of the deal — it's not a separate call you make, it happens because you called this. periodt.
