Subject: [RFC PATCH 10/17] btrfs-progs: add checksum type to checksumming functions
Date: Thu, 25 Jul 2019 11:33:57 +0200 [thread overview]
Message-ID: <71245b857a7214b284a57989fe677101c2ea13e5.1564046972.git.jthumshirn@suse.de> (raw)
In-Reply-To: <cover.1564046812.git.jthumshirn@suse.de>
In-Reply-To: <cover.1564046812.git.jthumshirn@suse.de>
Add the checksum type to csum_tree_block_size(), __csum_tree_block_size()
and verify_tree_block_csum_silent().
Signed-off-by: Johannes Thumshirn <jthumshirn@suse.de>
