dst_cache_reset(9)

💅 dst_cache_reset(9) — like, the Kernel API Manual bestie 🎀

okay so bestie, welcome to dst_cache_reset(9), straight out of the Kernel API Manual. it's a tiny little function and honestly it's giving "small but mighty" ✨ let's get into it.

---

🦋 NAME 🦋

dst_cache_reset — invalidate the cache contents 💀✨

---

🌸 SYNOPSIS 🌸

void dst_cache_reset (struct dst_cache *dst_cache );

no return value, no drama, just vibes 🫶

---

💖 ARGUMENTS 💖

• dst_cache — the cache 👑 that's it, that's the whole argument. it's the cache you're resetting. iconic.

---

🔥 DESCRIPTION 🔥

so here's the tea, bestie: this does not free the cached dst. and why? to avoid races and contentions 😭 — like, it's being polite and not causing chaos, we love that for it.

instead, the dst will be freed on a later cache lookup. so it's not gone-gone, it's just... later-gone. lowkey a procrastinator, highkey valid 💅

ngl this is the important bit: no freeing happens here. if you were expecting an immediate free, that is not this function, periodt. the actual free is deferred to a future cache lookup, fr fr.
