Qu Wenruo 08a3bd7694 btrfs-progs: tune: add the ability to generate new data checksums ... This patch would modify btrfs_csum_file_block() to handle csum type other than the one used in the current fs. The new data checksum would use a different objectid (-13) to distinguish with the existing one (-10). This needs to change tree-checker to skip the item size checks, since new csum can be larger than the original csum. After this stage, the resulted csum tree would look like this: item 0 key (CSUM_CHANGE EXTENT_CSUM 13631488) itemoff 8091 itemsize 8192 range start 13631488 end 22020096 length 8388608 item 1 key (EXTENT_CSUM EXTENT_CSUM 13631488) itemoff 7067 itemsize 1024 range start 13631488 end 14680064 length 1048576 Note the itemsize is 8 times the original one, as the original csum is CRC32, while target csum is SHA256, which is 8 times the size.
