  "message": "Btrfs: try to keep a healthy ratio of metadata vs data block groups\n\nThis patch makes the chunk allocator keep a good ratio of metadata vs data\nblock groups.  By default for every 8 data block groups, we\u0027ll allocate 1\nmetadata chunk, or about 12% of the disk will be allocated for metadata.  This\ncan be changed by specifying the metadata_ratio mount option.\n\nThis is simply the number of data block groups that have to be allocated to\nforce a metadata chunk allocation.  By making sure we allocate metadata chunks\nmore often, we are less likely to get into situations where the whole disk\nhas been allocated as data block groups.\n\nSigned-off-by: Josef Bacik \u003cjbacik@redhat.com\u003e\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n",
