mpt3sas_bas...e_mq_polling(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

okay so mpt3sas_base_pause_mq_polling — this is a Kernel API Manual page, section 9, and bestie it does exactly one thing: it pauses polling on the mq poll queues while the driver is flushing out the IOs. that's it. that's the whole gig. 🎀

✨ SYNOPSIS ✨

void mpt3sas_base_pause_mq_polling (struct MPT3SAS_ADAPTER *ioc );

like… yes, that space before the closing paren is actually there, don't come for me, copy it exactly fr fr 🫶

🦋 ARGUMENTS 🦋

  • ioc — the per adapter object 💖 the one and only thing you hand over

🌸 DESCRIPTION 🌸

so here's the vibe 😭 we're pausing polling on the mq poll (io uring) queues while the driver is flushing out the IOs. and why, you ask? because if we don't, we might see the race condition of completing the same IO from two paths. two paths. same IO. absolute chaos. not the main character energy we want 💀

⚠️ lowkey important: this is a race-condition guard. skip it and you're inviting the same IO to get completed twice. ngl that's a bad time for everyone. 🙈

and the return value? nothing. Returns nothing. no error code, no little gift, no nothing. void is void, periodt. 👑
