Description Mathieu Segaud 2005-01-09 18:16:11 UTC 
Linux kernel version 2.6.10 recently released exhibits slabinfo format version 2.1
so slabtop doesn't work anymore
However, 2.0 and 2.1 formats seem compatible wrt slabinfoXX function.
Trivial patch below solved the problem, however I do not know whether it is the right way (macros...).

I find this patch ugly. I guess a better fix could be introduced.
However, it works :)

A better short-term patch is:
-	if (major == 2 && minor == 0)
+	if (major == 2 && minor <= 1)

Until upstream puts out an update that uses the new nodeallocs field.

be nice if you mentioned the packages these things belong to ;)
Comment 4 SpanKY gentoo-dev 2005-01-12 17:21:50 UTC 
added patch from upstream cvs and released 3.2.4-r1

thanks regala & albert !
