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 or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Annotation

• Immediate include surface: `linux/tracepoint.h`, `trace/define_trace.h`.
• Detected declarations: `enum afs_fs_operation`, `enum afs_vl_operation`, `enum afs_cm_operation`, `enum yfs_cm_operation`, `enum afs_alist_trace`, `enum afs_call_trace`, `enum afs_cb_break_reason`, `enum afs_cb_promise_trace`, `enum afs_cell_trace`, `enum afs_dir_invalid_trace`.
• Atlas domain: Repository Root And Misc / include.
• 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.
