[dtrace-discuss] vfsstats.d limit probes to certain Filesystems

[Kevin Kramer]

I'd like to limit this to a few filesystems.

{
        this->fi_mount = args[0]->v_mount ?
                stringof(args[0]->v_mount->mnt_stat.f_mntonname) :
                        "<none>";
        @bytes[this->fi_mount, probefunc] = sum(this->delta);
        @ops[this->fi_mount, probefunc] = count();
}


I can't quite figure out where to place it. I keep getting errors on the 
conditional.

{
        this->fi_mount = args[0]->v_mount ?
                stringof(args[0]->v_mount->mnt_stat.f_mntonname) :
                        "<none>";
        /this->fi_mount == "/mnt/data/somedir"/ || this->fi_mount == 
"/mnt/data/someotherdir"/
        {
        @bytes[this->fi_mount, probefunc] = sum(this->delta);
        @ops[this->fi_mount, probefunc] = count();
        }

}
