Hello,

I want to check to which kernel version I need to upgrade to get a
certain feature.  For my case it was introduced in 0567a0c022d5b.

	zeisberg@cassiopeia:~/gsrc/linux-2.6$ rev=0567a0c022d5b343370a343121f38fd89925de55

	zeisberg@cassiopeia:~/gsrc/linux-2.6$ git name-rev --tags $rev
	0567a0c022d5b343370a343121f38fd89925de55 tags/v2.6.22~1686^2~1^3~5

	zeisberg@cassiopeia:~/gsrc/linux-2.6$ git name-rev --refs=*-rc1 $rev
	0567a0c022d5b343370a343121f38fd89925de55 tags/v2.6.22-rc1~1009^2~1^3~5

I don't now the underlaying algorithm, maybe it's to get a short string?

Anyhow I want to know the earliest tag that includes this patch?  Is
there something I missed?

I remember there was a similar discussion regarding describe.

BTW: gitk does the right thing, it says:

	Follows: v2.6.21-rc7
	Precedes: v2.6.22-rc1

(called with 

	zeisberg@cassiopeia:~/gsrc/linux-2.6$ gitk 0567a0c022d5b343370a343121f38fd89925de55^..0567a0c022d5b343370a343121f38fd89925de55
)

I didn't check how it does that though.

Best regards
Uwe
