Hi, due to a buggy bugfix to mkfs, filesystems created with version 4.1.1 are not entirely correct.
To check if the filesystem is affected run 'btrfs check' and look for Chunk[256, 228, 0]: length(4194304), offset(0), type(2) mismatch with block group[0, 192, 4194304]: offset(4194304), objectid(0), flags(34) Chunk[256, 228, 4194304]: length(8388608), offset(4194304), type(4) mismatch with block group[4194304, 192, 8388608]: offset(8388608), objectid(4194304), flags(36) at the beginning of the output. Such filesystems must not be used and must be recreated. Read-only mount should be safe to retrieve the data, but at the moment this hasn't been verified. Thanks to Qu Wenruo for identifying the problem, I'm sorry for the trouble.
