Dear hackers,

I'm interested in being able to display some data about the contents of 
the buffer cache , say file name and page offset (something like IRIX's 
'bufview').

Is there any utilities that do this currently? (searched around but 
didn't see anything in ports).

Assuming not, is it feasible to write one to do this? (if so, any 
pointers appreciated - massive FreeBSD internals newbie here....).

Cheers

Mark
