From bf34e7d952939b1d4289ef62e7d940fbd227c72a Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Mon, 2 Jan 2012 06:54:29 +0000 Subject: [PATCH] fat: reset VFAT short alias checksum on first match The VFAT short alias checksum read from a long file name is only overwritten when another long file name appears in a directory list. Until then it renders short file names invisible that have the same checksum. Reset the checksum on first match.
