From 5852c8b961542f997aa5aeee9c80e745e7af2d63 Mon Sep 17 00:00:00 2001 From: Johannes Thumshirn Date: Wed, 22 May 2019 10:18:58 +0200 Subject: [PATCH 1/1] btrfs: use btrfs_csum_data() instead of directly calling crc32c btrfsic_test_for_metadata() directly calls the crc32c() library function for calculating the CRC32C checksum, but then uses btrfs_csum_final() to invert the result. To ease further refactoring and development around checksumming in BTRFS convert to calling btrfs_csum_data(), which is a wrapper around crc32c().
