lc_try_lock(9)

🎀 NAME 🎀

okay bestie, welcome to the lc_try_lock(9) page from the Kernel API Manual ✨ this one is short and sweet:

lc_try_lock — variant to stop lc_get() from changing the tracked set 💅

---

✨ SYNOPSIS ✨

int lc_try_lock (struct lru_cache *lc );

---

🫶 ARGUMENTS 🫶

• lc — the lru cache to operate on 🌸

---

💖 DESCRIPTION 💖

Heads up, bestie: the reference counts and order on the active and lru lists may still change 👀

It only works on a "clean" set.

It returns true if we acquired the lock — which means there are no pending changes — and any further attempt to change the set will not succeed until the next lc_unlock 🔥

---

🦋 SEE ALSO 🦋

• Kernel file ./include/linux/lru_cache.h — also go peek at lc_try_lock_for_transaction(9), lc_unlock(9) 👑

mwah 💋 this little gem comes from ./include/linux, dated October 2026. bye bestie, go lock responsibly 🫶✨
