From 7073017aeb98db311ca407f0f552f2bfc1af3015 Mon Sep 17 00:00:00 2001 From: Johannes Thumshirn Date: Wed, 5 Dec 2018 15:23:03 +0100 Subject: btrfs: use offset_in_page instead of open-coding it Constructs like 'var & (PAGE_SIZE - 1)' or 'var & ~PAGE_MASK' can denote an offset into a page. So replace them by the offset_in_page() macro instead of open-coding it if they're not used as an alignment check.
