From b4f4473e8a88896c8ff12578183af0f099d33591 Mon Sep 17 00:00:00 2001 From: Miao Xie Date: Fri, 25 Oct 2013 17:30:45 +0800 Subject: [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.
