Subject: Re: Wrong -dirty suffix set by setlocalversion (was: BUG in git diff-index)
How about something like this? It ignores attributes that should have no
bearing on whether the kernel is considered dirty. Copied trees with no other
changes would no longer be marked with -dirty. Plus it works on read-only
media since no index updating is required.
Would this also be considered kosher, at least for the purposes of
setlocalversion?
