Thanks a lot for looking into our request.

The CONFIG_9P_FS_POSIX_ACL is needed for our newly added
ACL support, and FSCACHE can be delayed as it is optional to enable caching for now.
Once we add mmap support then we need that config option also for the mmap
functionality.
For now no need to enable CONFIG_9P_FSCACHE by default.

 CONFIG_NET_9P=y
 CONFIG_NET_9P_VIRTIO=m
 CONFIG_NET_9P_DEBUG=y
 CONFIG_9P_FS=y
 CONFIG_9P_FS_POSIX_ACL=y

Also this functionality is linked to taking latest QEMU from mainline. What are
the plans for
QEMU? Depending on QEMU version config options we need enable may change too.

Thanks,
JV
