SVN rev 203483 on 2010-02-04 07:55:42Z by zec
Instead of spamming the console on each curvnet recursion event, print
out each such call graph only once, along with a stack backtrace. This
should make kernels built with VNET_DEBUG reasonably usable again in
busy / production environments.
Introduce a new DDB command "show vnetrcrs" which dumps the whole log
of distinctive curvnet recursion events. This might be useful when
recursion reports get burried / lost too deep in the message buffer.
In the later case stack backtraces are not available.
