After fixing all compilati= on issues, the problem is still that it would try to allocate around hundred of megabytes of kernel memory (contiguous KVA), on any relatively modern machi= ne. Can you explain the high-level interface needed by lsof there? I do not see raw xvnode as anything useful, even for the utility like lsof. If somebody can explain what lsof needs, we perhaps can design proper API that is both useful and implementable. --=20 You are receiving this mail because: You are the assignee for the bug.=
