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.
- 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.
- Allocates kernel memory; connect allocation flags and lifetime to context constraints.
- Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

- Immediate include surface: `linux/init.h`, `linux/module.h`, `linux/mount.h`, `linux/nfs4_mount.h`, `linux/nfs_fs.h`, `linux/nfs_ssc.h`, `delegation.h`, `internal.h`.
- Detected declarations: `struct nfs_referral_count`, `function nfs4_write_inode`, `function open`, `function list_for_each_entry`, `function nfs_referral_loop_protect`, `function nfs_referral_loop_unprotect`, `function do_nfs4_mount`, `function nfs4_try_get_tree`, `function nfs4_get_referral_tree`, `function init_nfs_v4`.
- Atlas domain: Core OS / VFS And Filesystem Core.
- 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.
