re: CVS commit: src/sys

   Module Name: src
   Committed By:        elad
   Date:                Thu Dec 24 19:01:12 UTC 2009
   
   Modified Files:
        src/sys/kern: init_sysctl.c kern_sysctl.c
        src/sys/sys: file.h
   
   Log Message:
   When reporting open files using sysctl, don't use 'filehead' to fetch files,
   as we don't have a process context to authorize on. Instead, traverse the
   file descriptor table of each process -- as we already do in one case.
   
   Introduce a "marker" we can use to mark files we've seen in an iteration, as
   the same file can be referenced more than once.
   
   Hopefully this availability of filtering by process also makes life easier
   for those who are interested in implementing process "containers" etc.
