Subject: linux-user: initialize mmap_mutex properly
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=df377d0354b8572bd448e85afae72d43d6e071ab;p=qemu.git

linux-user: initialize mmap_mutex properly

We initialize mmap_mutex in any child threads/processes, but we need to
correctly statically initialize it for the original process.
