Description

If open_by_handle_at() is called in O_WRONLY or O_RDWR mode and then the file descriptor is closed, other lustre clients will still report ETXTBSY.

Example:

On cn16
=======
bschubert@cn16 ~>sudo ~/src/test/open-test /mnt/lustre_client-ES24/bschubert/ime/test7 1
Opened /mnt/lustre_client-ES24/bschubert/ime/test7/test7, fd: 4
Closed d: 4

Now on cn41
=========
bschubert@cn41 ~>/mnt/lustre_client-ES24/bschubert/ime//test7
-bash: /mnt/lustre_client-ES24/bschubert/ime//test7: Text file busy

test7 is just any file which has the the execution bit set.
