open command fails in UBIFS when pass O_DIRECT Flag

[naveen yadav]

Hi all,

I am using UBIFS file system, and i am able to read/write.
But when i use O_DIRECT flag it fails in open command. will you pls
let me know is it issue with UBIFS.
If i use jffs2 or other file system there is no problem.

Here is my test program

#define _GNU_SOURCE
#include <stdio.h>
#include <fcntl.h>
#include <sys/stat.h>

int main()
{
int w_fd=0;
if ((w_fd = open("temp.tmp", O_RDWR | O_CREAT |O_DIRECT , 0666)) < 0)
        {

                perror("fopen");

                return 0;
        }


}

Best Regards
Naveen
