>Description:
 The man page for flock(2) says that only error returned are
 EWOULDBLOCK, EBADF, and EINVAL.  Looking at the code in
 kern_descrip.c, it shows a return of EOPNOTSUPP.  The man page should
 be changed to reflect the current code.  This change broke mtools-3.0.
>How-To-Repeat:
	This code fragment has not been tested.  I looked at the
source to see the problem.
	int x, rc;
	x = open("/dev/fd0a", O_RDWR, 0666);
	rc = flock(x,LOCK_EX);
	errno is now set to EOPNOTSUPP.
>Fix:
	Change either the code in the kernel or the man page for flock(2).
