dst_cache_reset_now(9)

✨ NAME ✨

okay bestie, this is dst_cache_reset_now(9) from the Kernel API Manual — and it’s giving “invalidate the cache contents immediately.” 💅

dst_cache_reset_now — invalidate the cache contents immediately.

---

🌸 SYNOPSIS 🌸

yep, that’s the whole signature, no cap:

void dst_cache_reset_now (struct dst_cache *dst_cache );

---

🎀 ARGUMENTS 🎀

• dst_cache — the cache. that’s the one you’re dealing with, bestie 💖

---

🦋 DESCRIPTION 🦋

okay so real talk: the caller must be sure there are no concurrent users, because this frees all dst_cache users immediately, rather than waiting for the next per-cpu usage like dst_cache_reset does. 😭

most callers should use the higher speed lazily-freed dst_cache_reset function instead. that’s the main character here, fr fr. ✨
