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.
• Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.
• Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Annotation

• Immediate include surface: `linux/types.h`, `linux/inet.h`, `linux/slab.h`, `linux/sched/mm.h`, `linux/file.h`, `linux/blkdev.h`, `linux/delay.h`, `linux/kfifo.h`.
• Detected declarations: `function iscsi_sw_tcp_recv`, `function iscsi_sw_sk_state_check`, `function iscsi_sw_tcp_recv_data`, `function iscsi_sw_tcp_recv_data_work`, `function iscsi_sw_tcp_data_ready`, `function iscsi_sw_tcp_state_change`, `function iscsi_sw_tcp_write_space`, `function iscsi_sw_tcp_conn_set_callbacks`, `function iscsi_sw_tcp_conn_restore_callbacks`, `function iscsi_sw_tcp_xmit_segment`.
• Atlas domain: Driver Families / drivers/scsi.
• Implementation status: integration implementation candidate.
• Synchronization appears in or near this file; preserve lock ordering, sleepability, and interrupt-context constraints.

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.
