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

• No C-style include directives detected by the generator.

Detected Declarations

• struct fstrim_range
• struct xfs_mount
• struct xfs_busy_extents

Annotated Snippet

#ifndef XFS_DISCARD_H
#define XFS_DISCARD_H 1

struct fstrim_range;
struct xfs_mount;
struct xfs_busy_extents;

void xfs_discard_extents(struct xfs_mount *mp, struct xfs_busy_extents *busy);
int xfs_ioc_trim(struct xfs_mount *mp, struct fstrim_range __user *fstrim);

#endif /* XFS_DISCARD_H */

Annotation

• Detected declarations: `struct fstrim_range`, `struct xfs_mount`, `struct xfs_busy_extents`.
• 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.
