Hi, I have some large git repositories on a USB drive (ext3 file
system). That means that when replugging the drive, the recorded st_dev

structure gets reread as the stat data of all directories has changed.
That's a nuisance. Can't we have some heuristic or configuration option
where we, say, record the st_dev of the _index_ file, and if that has
changed, we propagate that change to the st_dev of its contents? I'd
like to see something that works more efficiently than rescanning the
whole disk every time I hibernate my computer.
Hmm. We shouldn't even be using st_dev any more.
How did you compile your git version? By default USE_STDEV should be off,
and it's been that way for a long time (because st_dev is also not
reliable on NFS etc).
