kunit_is_suppressed_warning(9)

💖 kunit_is_suppressed_warning(9) 💖

okay so this little icon is from the Kernel API Manual, and she is here to answer one very specific question: are warnings being suppressed by the current KUnit test? bestie, let’s get into it 🫶✨

---

✨ NAME ✨

kunit_is_suppressed_warning — check if warnings are being suppressed by the current KUnit test 💅

---

🌸 SYNOPSIS 🌸

bool kunit_is_suppressed_warning (bool count );

---

🎀 ARGUMENTS 🎀

• count — if true, increment the suppression counter on match. periodt 💖

---

🦋 DESCRIPTION 🦋

Returns true if the current task has active warning suppression. It uses the kunit_running static branch for zero overhead when no tests are running. no cap, that’s the whole vibe check ⭐

A single WARN*() may traverse multiple call sites in the warning path (e.g., __warn_printk and __report_bug). So here’s the tea: pass count = true at the primary suppression point to count each warning exactly once, and pass count = false at secondary points to suppress output without inflating the count. literally the main character energy of keeping the count correct 👑🔥
