The main thing that's been missing is time for me to review the patches, and a good way of writing regression tests that will work (or at least not fail) on build environments with a 32-bit time_t and 32-bit-only capable versions of functions such as gmtime(3). And given current discussions, I may want to think about some kind of superblock flag to allow the use of a 32-bit unsigned encoding for file systems using a 128-byte inode, with a way of setting that flag after scanning the file system to make sure there are no times that are previous to January 1, 1970. (Or more generally, allow any epoch to be defined using a 64-bit time_t offset stored in the superblock...)
