Why This File Exists

Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.

• Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.
• Touches IRQ or DMA behavior; this matters for the representative real-device path.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Annotation

• Immediate include surface: `linux/types.h`, `asm/byteorder.h`, `linux/bitops.h`, `linux/slab.h`.
• Detected declarations: `struct coalescing_timeset`, `struct common_queue_zone`, `struct eth_rx_prod_data`, `struct tcp_ulp_connect_done_params`, `struct iscsi_connect_done_results`, `struct iscsi_eqe_data`, `struct offload_pkt_dup_enable`, `struct pstorm_pkt_dup_cfg`, `struct regpair`, `struct rdma_eqe_destroy_qp`.
• Atlas domain: Core OS / Core Kernel Interface.
• Implementation status: source implementation candidate.
• IRQ or DMA behavior appears here, which is relevant to the selected PCIe/NVMe device path.

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.
