Subject: [CIFS] Add mmap for direct, nobrl cifs mount types
X-Git-Tag: firefly_0821_release~9833^2~2377^2~3

[CIFS] Add mmap for direct, nobrl cifs mount types

without mmap functions in file_ops OpenOffice can't save changes in
existing document. The same situation you can see with gedit. Also, a.out
format of files can't be executed without mmap.
