Hi there, While poring over <ufs/ffs/fs.h> in order to better understand the internals of FFS, I noticed that there is a number of comments in the file refering to a certain "filesystem address." There is also a macro named fsbtodb() for turning "filesystem block numbers into disk block addresses," according to its description. However, it seems to be the fragment size that actually serves as the filesystem addressing unit in all the relevant super-block fields, including fs_fsbtodb. Is my conclusion correct? If so, I'd rather clarify those comments, so new developers won't confuse fragments with blocks when doing RTFS. -- Yar
