I was reading the kernel code and docs and didn't find anything about some info like "cheksum type" as btrfs have for compression code. (I only found some silent "hack" in btrfs-progs, that print "checksum type", but get "checksum size")
If i understood all correctly btrfs only store checksum size, i.e. 4 for current CRC32C. May be that can be useful to rewrite some part of code and reuse checksum size, as checksum type. For backward compatibility current CRC32C size can be used for identify CRC32C. As that will not add any new checksum, that allow make that with zero "blood". And later if we add new checksum type, that possible to add compat flag for that. What you think?
