Description SATHEESARAN 2014-05-30 02:53:07 UTC 
Description of problem:
-----------------------
glfs_open doesn't recognize the O_CREAT flag as the open system call and hence
call to create new files with glfs_open() fails

Version-Release number of selected component (if applicable):
-------------------------------------------------------------
mainline

How reproducible:
-----------------
Always

Steps to Reproduce:
-------------------
1. use glfs_open() with O_CREAT flag to create a new file and to open it

Actual results:
---------------
glfs_open() fails with error message, "No such file or directory"

Expected results:
------------------
glfs_open() should create a file, if issued with O_CREAT flag


Additional info:
-----------------
Code snippet from the C program which uses libgfapi
<snip>

fd2 = glfs_open(fs1, file, O_WRONLY|O_SYNC|O_CREAT);
    if( fd2 == NULL ) {
        printf( "Error: %s\n",strerror(errno) );
        close( fd1 );
    }
