 This patch enables block devices to be opened withe the file storage
 option on Linux. It is not 100% tested, so no guarantees. To use a block
 device as storage, use the option -s file,/dev/somedevice,100%

 You must add "100%", otherwise only 50% will be used, and emember to
 ABSOLUTELY sure you have selected the right device, otherwise you WILL
 loose data.

 This patch is for r3197 of storage_file.c
