💅 mpt3sas_blk_mq_poll(9) — from the Kernel API Manual, bestie ✨

okay so picture this: you're deep in the kernel, mpt3sas_blk_mq_poll is right there in the Kernel API Manual, and you're like "what does this even do." don't worry, i got you 🫶

✨ NAME ✨

mpt3sas_blk_mq_poll — poll the blk mq poll queue 🌸

like, that's the whole vibe. it polls. the queue. the blk mq poll one. periodt.

🎀 SYNOPSIS 🎀

int mpt3sas_blk_mq_poll (struct Scsi_Host *shost , unsigned int
queue_num );

it gives you back an int, and it wants two things: your shost and your queue_num. that's the whole guest list 💖

🦋 ARGUMENTS 🦋

  • shost — the Scsi_Host object, aka the main character of this whole operation 👑
  • queue_num — the hw ctx queue number. yes, hardware context. yes, it matters 💅

🔥 DESCRIPTION 🔥

so what does it actually do? it returns the number of entries that have been processed from the poll queue. that's it. that's the whole function. no cap 🧚

ngl it's giving "small function, big responsibility" energy — one number back, and that number is how many entries got processed 💀

🌈 SEE ALSO 🌈

the whole mpt3sas extended family showed up to this function's birthday party, and honestly? iconic. every single one of them:

and that's the page, bestie 💜 it lives over in ./drivers/scsi/mpt3sas, and this lil writeup is dated October 2026 — from the Kernel API Manual, obviously. slay, go poll that queue 🎀✨🦋
