Problem Description: 
when we run fcntly System call with F_SETLEASE and F_RDLCK options set fcntly 
comes out with error no 11 (Try Again). But the problem is noticed even after 
running the test several times and withour success. 
====================================== 
Steps to reproduce: 
Run: 
 
int main() 
{ 
int fd; 
int returnValue; 
if ((fd = open("tmp_file",O_RDWR|O_CREAT,0777)) == -1) 
{ 
        printf("File opening Failed"); 
        exit(0); 
} 
returnValue=fcntl(fd,F_SETLEASE,F_RDLCK); 
printf("\n fcntl Return Value:%d",returnValue); 
printf("\n Error No: %d", errno); 
printf("\n"); 
}
