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.
• Defines an operation table; this is where Linux turns generic core objects into subsystem-specific behavior.
• 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.

Dependency Surface

• linux/fs.h
• linux/magic.h

Annotation

• Immediate include surface: `linux/fs.h`, `linux/magic.h`, `linux/uuid.h`, `linux/mutex.h`, `linux/rwsem.h`, `linux/kobject.h`.
• Detected declarations: `struct zonefs_zone`, `struct zonefs_zone_group`, `struct zonefs_inode_info`, `struct zonefs_super`, `struct zonefs_sb_info`, `enum zonefs_ztype`, `enum zonefs_features`, `function zonefs_zone_type`, `function zonefs_zone_is_cnv`, `function zonefs_zone_is_seq`.
• Atlas domain: Core OS / VFS And Filesystem Core.
• Implementation status: pattern 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.
