Nobody was using this function?

GetDeviceAndInode would make more sense to me.

   base::ThreadRestrictions::AssertIOAllowed();  // For call to stat().
   struct stat buffer;
   int result = stat(path.value().c_str(), &buffer);
   if (result < 0)
     return false;
 
+  *dev = buffer.st_dev;
   *inode = buffer.st_ino;
   return true;
