Guess, maybe he isn't reading the @thunk.org email anymore which was reference in the e2fsprogs source I used. Ted, from ext2_fs.h I learn that the value 0x0020 is left unused. #define EXT2_FEATURE_INCOMPAT_META_BG 0x0010 #define EXT3_FEATURE_INCOMPAT_EXTENTS 0x0040 #define EXT4_FEATURE_INCOMPAT_64BIT 0x0080 Is this intentionally?
