[Qemu-devel] [PULL 1/2] block/ssh: fix possible segmentation fault when .desc is not null-terminated
[PULL 2/3] contrib/vhost-user-blk: add missing GOptionEntry NULL terminator
1
From: Murilo Opsfelder Araujo <muriloo@linux.vnet.ibm.com>
1
The GLib documentation says "a NULL-terminated array of GOptionEntrys"
2
so we'd better make sure there is a terminator that lets
3
g_option_context_add_main_entries() know when the end of the array has
4
been reached.

[Qemu-devel] [PULL 2/2] iotests: Make 200 run on tmpfs
[PULL 3/3] virtiofsd: Add docs/helper for killpriv_v2/no_killpriv_v2 option

From: Max Reitz <mreitz@redhat.com>

200 currently fails on tmpfs because it sets cache=none. However,
3
virtiofsd has introduced killpriv_v2/no_killpriv_v2 for a while. Add
4
without that (and aio=native), the test still works now and it fails
4
description of it to docs/helper.
5
before Jeff's series (on fc7dbc119e0852a70dc9fa68bb41a318e49e4cd6). So
6
we can probably remove the aio=native safely, and replace cache=none by
7
cache=$CACHEMODE.
