Btrfs-progs: don't output baffling message when checking a fresh fs
As we know, a new fs doesn't have space cache, so we set the cache generation of the super block to be -1ULL, it is not equal to the fs generation. But the check program didn't consider this case, and output the following message cache and super generation don't match, space cache will be invalidated directly, it would be baffling the users. So we should avoid outputing such message. This patch fixes this problem. Signed-off-by: Miao Xie <> Signed-off-by: David Sterba <> Signed-off-by: Chris Mason <>
