I'm currently trying to use the gadget mass storage function to present a FAT32 partition on an SD card as a mass storage device to Windows. I have been successful in setting up the mass storage module in this way by using the block device. I can copy files to and from Windows and see them on the device where I have mounted the block device also. However, the file system statistics (accessed by using statvfs) do not seem to update. I can remove files from windows and the f_bfree number does not change. I've also used 'df' and have seen the same result. I believe this is because the VFS does not know that the mass storage gadget has changed the file system since the mass storage gadget is only using it as a block device. Is there a way to notify the VFS that the file system has changed? Is there a better way to share a file system between Windows and the device? Is there another way to know the amount of free space on the file system?
