Why This File Exists

Part of the selected hardware vertical slice: PCI discovery, driver binding, NVMe queues, block requests, DMA, interrupts, and completion.

• Part of the selected hardware vertical slice: PCI discovery, driver binding, NVMe queues, block requests, DMA, interrupts, and completion.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/compat.h
• uapi/linux/blkpg.h

Detected Declarations

• struct blkpg_compat_ioctl_arg

Annotation

• Immediate include surface: `linux/compat.h`, `uapi/linux/blkpg.h`.
• Detected declarations: `struct blkpg_compat_ioctl_arg`.
• Atlas domain: Representative Device Path / PCIe NVMe Storage Path.
• Implementation status: source implementation candidate.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
