Pass the get_real_filename operation through the VFS
This is done to help file systems that can tell us about the real upper/lower case combination given a case-insensitive file name. The sample I will soon push is the gpfs module (recent gpfs has a get_real_filename function), others might have a similar function to help alleviate the 1million files in a single directory problem. Jeremy, please comment! Thanks, Volker
