Good guess, with that patch no bug :)

Ah that's the node of the story.
I made 2 tries :
 (1) mount the SD card, create a folder "toto", umount
     => when checked in my laptop, no new folder is created
 (2) mount the SD card, create a folder "toto", and copy in it a file "foo.txt",
 umount
     => when checked in my laptop, both the directory and the file *are* there

So I suppose that creating a directory without any file within doesn't trigger
the write on the device.

Thanks for your help.

Cheers.
