💅 ibmvscsis_cmd_q_dequeue — Get valid Command element 💅

okay so bestie, we are lowkey in the Kernel API Manual right now, and this page is all about ibmvscsis_cmd_q_dequeue. It's giving "grab a valid command element from the queue" energy, and honestly? Iconic. 🎀

✨ SYNOPSIS ✨

struct viosrp_crq * ibmvscsis_cmd_q_dequeue (uint mask , uint
       *current_index , struct viosrp_crq *base_addr );

🍓 ARGUMENTS 🍓

• mask — Mask to use in case index wraps. That's the whole job, no cap.
• current_index — Current index into command queue. Literally the index, bestie.
• base_addr — Pointer to start of command queue. The main character starting address, periodt.

🦋 DESCRIPTION 🦋

Returns a pointer to a valid command element or NULL, if the command queue is empty. So yeah: valid command element? Slay. Empty queue? You get NULL, and that's the vibe check. 💖

EXECUTION ENVIRONMENT: Interrupt environment, interrupt lock held.

Like, respect the environment, okay? It's interrupt environment and the interrupt lock is held. No funny business. 🙈

🌈 SEE ALSO 🌈

Kernel file: ./drivers/scsi/ibmvscsi_tgt/ibmvscsi_tgt.c — that's where the lore lives, bestie.
