Subject: [Qemu-devel] [PATCH v2 0/1] Allow the building of VirtFS to be disabled
Date: Thu, 9 Feb 2012 20:06:32 -0600	[thread overview]
Message-ID: <1328839593-2701-1-git-send-email-meadori@codesourcery.com> (raw)

There have been reports [1, 2] where folks have had issues building
VirtFS and the virtio backend on older systems.  I personally saw
problems due to the use of features (struct statfs f_frsize field,
fdopendir, O_NOATIME) in this code that are not available on much older
Linux systems.  Given, the system I ran into this on is ancient (RH8 sysroot),
but I still need to build QEMU on it nonetheless.

This patch adds a new configure option for disabling the building of
VirtFS all together.  Tested by building with and without --disable-virtfs
on older (RH8 sysroot) and newer systems (x64 Fedora 16).

* Changes from v1
  - Simplify the configure logic and support the standard behavior
    of defaulting virtfs="".  Changes suggested by Peter Maydell.
