vb2_queue_release(9)

🌸 NAME 🌸

vb2_queue_release — stop streaming, release the queue and free memory. Okay so this is vb2_queue_release(9) from the Kernel API Manual, and it's literally the cleanup bestie for a videobuf2 queue 💖.

💅 SYNOPSIS 💅

void vb2_queue_release (struct vb2_queue *q );

🫶 ARGUMENTS 🫶

• q — pointer to struct vb2_queue with videobuf2 queue. Yes, that's the queue getting the release treatment ✨.

🧚 DESCRIPTION 🧚

This function stops streaming and performs necessary clean ups, including freeing video buffer memory. It's giving cleanup era, and yes — it frees the video buffer memory too 💅.

Bestie, listen: the driver is responsible for freeing the vb2_queue structure itself. This function does not do that part — don't forget it, or that's a leak vibe 😭.
