Sort of a feature proposal

[David Kastrup <dak@gnu.org>]

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
data in the index is off, meaning that the whole repo directory
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.

Thanks,
