It's unfortunately not true that everything handles this correctly.
32-bit binaries for games on Steam that use stat() without the 64 is
so prevalent that I got tired of adding the LD_PRELOAD wrapper script
and just patched out the EOVERFLOW return from glibc instead. (They
obviously don't care about the inode value at all, and I don't use any
other 32-bit binaries that do). This is probably a class of binaries
you don't care very much about, and not very likely to be installed on
a tmpfs that has wrapped around, but I thought it was worth mentioning
that they do exist anyway.
Thank you for alerting us to reality, Mikael: not what any of us wanted
to hear, but we do care about them, and it was well worth mentioning.
