If you take out that line, other things using lockfp ought to complain about that variable not even existing.
And what the rest of the code does is certainly important. There may be bugs that misinterpret its return value, for instance.
Can we please see more of the code?
Also, a df -h just to make sure /var/lock/subsys/ isn't some odd filesystem that even root can't write to.
