Why This File Exists

Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.

• Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.
• Defines or participates in a user/kernel boundary; inspect argument validation, copy_from_user/copy_to_user, credentials, and dispatch target.

Dependency Surface

• stdio.h
• errno.h
• string.h
• sys/wait.h
• kselftest.h

Detected Declarations

• function acct

Annotated Snippet

if (sz <= 0) {
			ksft_test_result_fail("Terminated child process not logged\n");
			ksft_exit_fail();
			return 1;
		}

		ksft_test_result_pass("Successfully logged terminated process.\n");
		fclose(fp);
		ksft_exit_pass();
		return 0;
	}

	return 1;
}

Annotation

• Immediate include surface: `stdio.h`, `errno.h`, `string.h`, `sys/wait.h`, `kselftest.h`.
• Detected declarations: `function acct`.
• Atlas domain: Support Tooling And Documentation / tools.
• Implementation status: core 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.
