   Sorry, I disagree here...GETLK is really a misnomer, IMO. TESTLK
   would have been a better name.

   GETLK are used is to "get the first lock".

   It's a way to test whether a particular lock can be applied, and to
   return information about a conflicting lock if it can't. If, for
   instance there is no conflicting lock, then you don't "get" any
   lock information back (l_type just gets reset to F_UNLCK).

While I kinda see your point, it isn't what GETLK does; it really does
get you information about the first lock -- you're not testing
anything.  It is also the terminology used in the POSIX standard.
