Hi all, As some already know, we are implement btrfs in-band de-duplication. And we already have a working and stable version internal. But that's filesystem wide de-duplication. Now we hope to add support to enable/disable dedup per-file. Much like current NODATACOW/NOCOMPRESS for inode. But we are not sure where to add such flag. Here is our current ideas: 1) XATTR Make a btrfs internal xattr, just like some btrfs prop. 2) inode flag, like FS_NOCOMP_FL Although only btrfs is going to support in-band dedup, who knows what will happen in future? Any advice is welcomed.
