From 21b9dec990b08a104600bf8e408e64e805a02835 Mon Sep 17 00:00:00 2001 From: Volker Lendecke Date: Wed, 10 Dec 2008 03:17:19 +0100 Subject: 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!
