Hello, I am working on a software which has its own code to mount file systems, but when working on adding ext4 support I just noticed something strange. The ext2/3 reader already works quite well for ext4! Also: EXT2_SUPER_MAGIC == EXT3_SUPER_MAGIC == EXT4_SUPER_MAGIC So does anyone know what is the best way to differentiate in a file system reader between ext3 and ext4? The best I came up so far would be checking the size of the superblock ... for ext3 it seams to be smaller I think ... but I guess people here might have better ideas. thanks, Felipe Monteiro de Carvalho -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
