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.

Annotation

• Immediate include surface: `linux/blkdev.h`, `linux/backing-dev.h`, `linux/vfs.h`, `linux/fs_struct.h`, `linux/sched/mm.h`, `linux/fs_context.h`, `linux/fs_parser.h`, `sysctl.h`.
• Detected declarations: `function ntfs_parse_param`, `function ntfs_reconfigure`, `function ntfs_handle_error`, `function instead`, `function ntfs_set_volume_flags`, `function ntfs_clear_volume_flags`, `function ntfs_write_volume_label`, `function is_boot_sector_ntfs`, `function parse_ntfs_boot_sector`, `function cluster`.
• 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.
