From 9e5e6d4e2e5e37e28bf2be85fa08761e33aa5efb Mon Sep 17 00:00:00 2001 From: David Sterba Date: Mon, 31 Oct 2022 20:33:40 +0100 Subject: btrfs: zlib: use copy_page for full page copy The copy_page helper may use an optimized version for full page copy (eg. on s390 there's a special instruction for that), there's one more left to convert.
