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

Dependency Surface

• ../glob.h

Detected Declarations

• struct ksmbd_user
• function user_guest
• function set_user_flag
• function test_user_flag
• function set_user_guest
• function user_uid
• function user_gid

Annotation

• Immediate include surface: `../glob.h`.
• Detected declarations: `struct ksmbd_user`, `function user_guest`, `function set_user_flag`, `function test_user_flag`, `function set_user_guest`, `function user_uid`, `function user_gid`.
• Atlas domain: Core OS / VFS And Filesystem Core.
• 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.
