From 80ba4caf8ba92bb8f852b5e09251274c11e4b647 Mon Sep 17 00:00:00 2001 From: Mark-PK Tsai Date: Sat, 7 Oct 2023 15:05:53 +0800 Subject: zram: use copy_page for full page copy Some architectures, such as arm, have implemented optimized copy_page for full page copying. Replace the full page memcpy with copy_page to take advantage of the optimization.
