💅 calipso_cache_entry_free(9)

okay so bestie, welcome to the Kernel API Manual ✨ — this one lives in calipso_cache_entry_free(9) land and it's literally about one thing: yeeting a cache entry into the void. 🦋

🌸 SYNOPSIS 🌸

void calipso_cache_entry_free (struct calipso_map_cache_entry *entry );

that's it. that's the whole vibe check. one arg, no return value, no drama. 👑

🎀 ARGUMENTS 🎀

  • entry — the entry to free 💖 like, the actual cache entry you're about to release back into the wild. this is the main character of the function, fr fr.

✨ DESCRIPTION ✨

so here's the tea, bestie 🍓 — this function frees the memory associated with a cache entry. and it's not just the entry itself, no ma'am: it also handles the LSM cache data, but only if there are no longer any users. 👀

"no longer any users" means reference count == 0. periodt. if the refcount isn't zero, the LSM cache data stays put — we don't touch it. 🔥

ngl this is the important bit: the LSM cache data only gets freed when reference count == 0. don't forget it, iykyk 💅
