Subject: Btrfs: output warning instead of error when loading free space cache failed
From: Miao Xie <miaox@xxxxxxxxxxxxxx>
commit 32d6b47fe6fc1714d5f1bba1b9f38e0ab0ad58a8 upstream.
If we fail to load a free space cache, we can rebuild it from the extent tree,
so it is not a serious error, we should not output a error message that
would make the users uncomfortable. This patch uses warning message instead
of it.
