KUNIT_SUPPRE...ARNING_COUNT(9)

💖 NAME 💖

okay so welcome to the KUNIT_SUPPRESSED_WARNING_COUNT(9) page from the Kernel API Manual, bestie!! The header banner is doing the truncated KUNIT_SUPPRE...ARNING_COUNT(9) thing, but the actual name is KUNIT_SUPPRESSED_WARNING_COUNT — and it literally returns the suppressed warning count. No cap. 💅

✨ SYNOPSIS ✨

KUNIT_SUPPRESSED_WARNING_COUNT

🫶 DESCRIPTION 🫶

okay here’s the actual tea ☕: this returns the number of WARN*() calls suppressed since the current suppression block started. If the handle is NULL, it returns 0 — yes, literally 0, not a vibe check fail. It’s usable inside a kunit_warning_suppress block. That’s the whole adorable contract. ✨
