okay bestie, buckle up, we're in the MIPS bitops corner of the kernel and honestly? it's giving iconic low-level energy ✨

🌸 NAME 🌸

__mips_test_and_clear_bit — clear a bit and return its old value. literally that's it, that's the whole vibe 🎀

And to be super clear (pun fully intended, i'm hilarious): this one gets called by test_and_clear_bit() whenever that function can't find a faster solution. it's the fallback bestie, the reliable one, the one who shows up when nobody else can 🫶

*addr );

🦋 ARGUMENTS 🦋

• nr — the bit you wanna clear 🔥 like, which one. this one.
