[Qemu-devel] PATCH: block-vvfat.c: fix parse_long_name

[Tristan Gingold]

Hi,

if a long_file_name length is a multiple of 13, no NUL terminator is  
appended to the internal name.  As a
consequence garbled names can be written on the disk.
This patch makes sure a NUL terminator is always appended.

Tristan.
