[PATCH] 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.
