Subject: raw-win32.c: Fix incorrect handling behaviour of small block files
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=56e023af805215260c71d44f5b5a98087f4920d2;p=qemu.git

raw-win32.c: Fix incorrect handling behaviour of small block files

It is a valid case that the read data's size is smaller than the
requested size since there could be files that are smaller than
the minimum block size (For ex. when a VMDK disk descriptor file)
