Subject: [RFC PATCH 06/17] btrfs-progs: don't blindly assume crc32c in csum_tree_block_size()
Date: Thu, 25 Jul 2019 11:33:53 +0200	[thread overview]
Message-ID: <ae31ea458aff801cbd9d0674431019314834c64f.1564046972.git.jthumshirn@suse.de> (raw)
In-Reply-To: <cover.1564046812.git.jthumshirn@suse.de>
In-Reply-To: <cover.1564046812.git.jthumshirn@suse.de>

The callers of csum_tree_block_size() blindly assume we're only having
crc32c as a possible checksum and thus pass in
btrfs_csum_sizes[BTRFS_CSUM_TYPE_CRC32] for the size argument of
csum_tree_block_size().
