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.
• 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.

Dependency Surface

• linux/hugetlb.h
• linux/hugetlb_cgroup.h

Detected Declarations

• function hstate_is_gigantic_no_runtime
• function next_node_allowed
• function get_valid_node_allowed
• function hstate_next_node_to_alloc
• function remove_pool_hugetlb_folio
• function hugetlb_sysctl_init

Annotation

• Immediate include surface: `linux/hugetlb.h`, `linux/hugetlb_cgroup.h`.
• Detected declarations: `function hstate_is_gigantic_no_runtime`, `function next_node_allowed`, `function get_valid_node_allowed`, `function hstate_next_node_to_alloc`, `function remove_pool_hugetlb_folio`, `function hugetlb_sysctl_init`.
• Atlas domain: Core OS / Memory Management.
• 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.
