vfat: bug fix for vfat cannot handle filename with 255 2008-04-28T15:58:47+00:00 Keith Mok ek9852@gmail.com 2008-04-28T09:16:29+00:00 f22032ba8de2960a64a3dd9719fb5c99b1f1ae6e This patch fix the problem that the buffer allocated for convert of unicode to utf8 in fat/dir.c is too small. And cannot handle filename with 255 asian characters when mounted with utf8 options. Also it fix the filename length limitation checking in vfat/namei.c that the filename length should be checked against the number of converted unicode characters. Not the length before NLS/UTF8 converted.
