Why This File Exists

Top-level or miscellaneous repository surface. Use this as map coverage unless a later manual pass promotes the file into a deeper subsystem dossier.

• Top-level or miscellaneous repository surface. Use this as map coverage unless a later manual pass promotes the file into a deeper subsystem dossier.
• Defines an operation table; this is where Linux turns generic core objects into subsystem-specific behavior.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/blk_types.h
• linux/device.h
• scsi/scsi_cmnd.h

Detected Declarations

• struct module
• struct request
• struct scsi_driver

Annotation

• Immediate include surface: `linux/blk_types.h`, `linux/device.h`, `scsi/scsi_cmnd.h`.
• Detected declarations: `struct module`, `struct request`, `struct scsi_driver`.
• Atlas domain: Repository Root And Misc / include.
• Implementation status: pattern 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.
