panthor_sub..._sync_signal(9)

✨ panthor_submit_ctx_search_sync_signal(9) ✨

okay bestie, so this one lives in the Kernel API Manual, section 9 — it's a kernel-side function and it's literally just a little detective. it goes looking for a sync signal operation that's already hanging out in a submit context. no cap, that's the whole gig 🕵️‍♀️💅

🦋 ARGUMENTS 🦋

• ctx — the context you're searching the signal operation in. like, the group chat you're scrolling through 🔍
• handle — the syncobj handle. your search key, bestie 🎯
