Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

• Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/types.h
• scsi/iscsi_proto.h

Detected Declarations

• struct iscsit_cmd
• struct iscsit_conn
• struct iscsi_datain_req
• struct iscsi_ooo_cmdsn
• struct iscsi_pdu
• struct iscsit_session

Annotation

• Immediate include surface: `linux/types.h`, `scsi/iscsi_proto.h`.
• Detected declarations: `struct iscsit_cmd`, `struct iscsit_conn`, `struct iscsi_datain_req`, `struct iscsi_ooo_cmdsn`, `struct iscsi_pdu`, `struct iscsit_session`.
• Atlas domain: Driver Families / drivers/target.
• 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.
