(In reply to Mark Johnston from comment #2)

> NAMEI events are generated by namei().  symlink(2) doesn't call namei() o=
n the second parameter, so this patch doesn't really make sense.

vn_getcwd() and few other places call ktrnamei().
I do not understand why call ktrnamei() directly is wrong.


> ktrace(2) in general does not show you arbitrary system call parameters.

It is enough for my purposes to get few NAMEI, like:
    47 ktrace   CALL  execve(0x7fffffffdfb6,0x7fffffffd970,0x7fffffffd980)
    47 ktrace   NAMI  "build-install_media.sh"
    47 ktrace   NAMI  "/bin/sh"
    47 ktrace   NAMI  "/libexec/ld-elf.so.1"
    47 sh       RET   execve JUSTRETURN

> But if you want to see parameters, you can also just use truss or dtrace.

I need get list of all files that was read with abs path.
I wrote tool to parse ktrace file, it keep context of process and convert p=
ath
to abs on logging and filter crap out of src dir.
I can not use truss without modifications to get same results.
