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

• linux/mempool.h

Detected Declarations

• struct ceph_msgpool

Annotated Snippet

struct ceph_msgpool {
	const char *name;
	mempool_t *pool;
	int type;               /* preallocated message type */
	int front_len;          /* preallocated payload size */
	int max_data_items;
};

int ceph_msgpool_init(struct ceph_msgpool *pool, int type,
		      int front_len, int max_data_items, int size,
		      const char *name);
extern void ceph_msgpool_destroy(struct ceph_msgpool *pool);
struct ceph_msg *ceph_msgpool_get(struct ceph_msgpool *pool, int front_len,
				  int max_data_items);
extern void ceph_msgpool_put(struct ceph_msgpool *, struct ceph_msg *);

Annotation

• Immediate include surface: `linux/mempool.h`.
• Detected declarations: `struct ceph_msgpool`.
• Atlas domain: Core OS / Core Kernel Interface.
• 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.
