mpi3mr_blk_mq_poll(9)

💅 NAME 💅

mpi3mr_blk_mq_poll — Operational reply queue handler. Okay so this is the mpi3mr_blk_mq_poll(9) page from the Kernel API Manual, and it's giving small function, very important kernel business energy. 💖

✨ SYNOPSIS ✨

int mpi3mr_blk_mq_poll (struct Scsi_Host *shost , unsigned int queue_num
);

No cap, that's the whole signature. Obsessed. ✨

🎀 ARGUMENTS 🎀

• shost — SCSI Host reference. It's the host side of the situation, bestie.
• queue_num — Request queue number (w.r.t OS it is hardware context number). So same queue, just with the OS-flavored naming situation.

🌸 DESCRIPTION 🌸

So what this does is check the specific operational reply queue and drain the reply queue entries until the queue is empty, processing the individual reply descriptors along the way. That's the vibe: reply queue gets emptied, descriptors get handled, we move on. 🫶

🔥 RETURN 🔥

Returns 0 if the queue is already processed, or the number of reply descriptors processed. So yeah: zero means "already handled," and otherwise you get a count of the reply descriptors that got processed. ✨
