dtrace and kernel modules

[Julian Elischer]

I'm specifically interested in the case of kernel modules that 
instantiate new syscalls.

How much support do we have for that?  In the one example in our 
sources of a kld with a syscall (kgssapi.ko) dtrace seems to find 
regular function entrypoints but not the syscall.


root at porridge:/usr/src # dtrace -n ":kgssapi::entry {}"
dtrace: description ':kgssapi::entry ' matched 138 probes
^C

root at porridge:/usr/src # dtrace -n "syscall:kgssapi::entry {}"
dtrace: invalid probe specifier syscall:kgssapi::entry {}: probe 
description syscall:kgssapi::entry does not match any probes
root at porridge:/usr/src #


Do we have plans to support dynamic syscall support?
