Annotated Snippet

#ifndef _LINUX_MSDOS_FS_H
#define _LINUX_MSDOS_FS_H

#include <uapi/linux/msdos_fs.h>

/* media of boot sector */
static inline int fat_valid_media(u8 media)

	return 0xf8 <= media || media == 0xf0;
}
#endif /* !_LINUX_MSDOS_FS_H */

Annotation

• Immediate include surface: `uapi/linux/msdos_fs.h`.
• Detected declarations: `function fat_valid_media`.
• 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.
