From 094e320d761dae5816d8faa695b0509eea79c108 Mon Sep 17 00:00:00 2001 From: OGAWA Hirofumi Date: Fri, 31 Mar 2006 02:30:53 -0800 Subject: [PATCH] [PATCH] fat: kill reserved names Since these names on old MSDOS is used as device, so, current fat driver doesn't allow a user to create those names. But many OSes and even Windows can create those names actually, now. This patch removes the reserved name check.
