🌸 dm_mst_test_msg_ready_mask(9) 🌸

okay bestie, welcome to the Kernel API Manual page for dm_mst_test_msg_ready_mask — it's giving kernel-test realness and I'm obsessed. 💅

---

🌟 NAME 🌟

dm_mst_test_msg_ready_mask — ESI mask selection per message-ready type. no cap, that's the whole vibe. ✨

---

🦋 SYNOPSIS 🦋

void dm_mst_test_msg_ready_mask (struct kunit *test );

---

🎀 ARGUMENTS 🎀

• test — the KUnit test context. that's it, that's the argument, bestie 🫶

---

💖 DESCRIPTION 💖

so here's the tea: DOWN_REP and UP_REQ each select their single bit. every other type? it selects both. that's the mask-selection moment, and honestly? iconic. 🔥
