Subject: [PATCH v2 0/1] mm/contpte: Optimize loop to reduce redundant operations
Date: Tue,  8 Apr 2025 16:58:08 +0800	[thread overview]
Message-ID: <20250408085809.2217618-1-xavier_qy@163.com> (raw)
In-Reply-To: <027cc666-a562-46fa-bca5-1122ea00ec0e@arm.com>

Hi Dev,

Thanks for your valuable feedback earlier. I have optimized the patch again,
 eliminating additional boolean variables check and allowing the loop to break
 immediately once both dirty and young flags are set. This approach should
 theoretically be more efficient than the original code. Thank you for taking
 the time to review this work, I'm happy to make further adjustments based on
 your suggestions!
