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/types.h

Detected Declarations

• struct qnap_mcu
• struct qnap_mcu_variant

Annotated Snippet

struct qnap_mcu_variant {
	u32 baud_rate;
	int num_drives;
	int fan_pwm_min;
	int fan_pwm_max;
	bool usb_led;
};

int qnap_mcu_exec(struct qnap_mcu *mcu,
		  const u8 *cmd_data, size_t cmd_data_size,
		  u8 *reply_data, size_t reply_data_size);
int qnap_mcu_exec_with_ack(struct qnap_mcu *mcu,
			   const u8 *cmd_data, size_t cmd_data_size);

Annotation

• Immediate include surface: `linux/types.h`.
• Detected declarations: `struct qnap_mcu`, `struct qnap_mcu_variant`.
• 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.
