I am building a tool to identify the file that has a specific LBA. The approach I am using is to search through each inode from number 2 up. This approach works well with UFS1 file systems as then preinitialize all the inodes. However, UFS2 does lazy inode initialization so there are always some that are basically garbage. I have not found any relaiable way to determine from the inode contents if it is in use or not. I suspect that information is in the inode bit map. However, I haven't found any way to access that. Nothing in ffs.h seems to fit the need. Is there a way to tell if inode x is initialized or in use?
