Some file managers try to set permissions and time for files during the operations on the mounted ObexFS file system and get errors.
Krusader is the example. I was uploading a large set of files to my Nokia phone and it displayed the error message about being unable to set permissions on each copied file. It was very annoying to click on the OK button many many times.
I propose to insert several dummy functions just to satisfy the requirements of such pedantic file managers.
Patch is based on the version 0.12 of the ObexFS
