Subject: Mini-OS: fix 9pfs stat receive format
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=02c0e51fc9ab7cf404414431de224a62a62f558d;p=people%2Faperard%2Fmini-os.git

Mini-OS: fix 9pfs stat receive format

The format string of the received data for the 9pfs stat command is
missing the initial 2 byte total length specifier. Add it.

Fixes: 2d1dfccd3aa3 ("Mini-OS: add read and write support to 9pfsfront")
