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@porridge:/usr/src # dtrace -n ":kgssapi::entry {}"
dtrace: description ':kgssapi::entry ' matched 138 probes
^C
root@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@porridge:/usr/src #
Do we have plans to support dynamic syscall support?
