Subject: trace: avoid Python 2.5 all() in tracetool
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=73735f72188bd5fe25c3478aa4a2f1a17cb878d8;p=qemu.git

trace: avoid Python 2.5 all() in tracetool

Red Hat Enterprise Linux 5 ships Python 2.4.3.  The all() function was
added in Python 2.5 so we cannot use it.
