Hi,
Compiling KVM-87 failed with following error:
make -C /lib/modules/2.6.29-gentoo-r5/build M=`pwd` \
LINUXINCLUDE="-I`pwd`/include -Iinclude \
-Iarch/x86/include -I`pwd`/include-compat \
-include include/linux/autoconf.h \
-inclu
The -Wunused-result is the default option of gcc, so no need to
add it to the FLAGS.
And the previous version of gcc can't support this flag, it may
cause a compile error.

My idea is adding a new function dtor pointer and some other args
pointers to the struct skb_shared_info. If skb_shared_info.dtor
exists, the pages in skb_shared_info.frags are private to this
skb->head. Anyone who wants to get these pages, should copy them
instead.

kernel no matter we want to use a separate outside module or not. This

Wait while we inventory system:

These two patches are based on the multi-queue virtio-scsi patch set.
We set cpu affinity when the num_queues equals to the number
of VCPUs. Split out the set affinity function, this also
fix the bug when CPU IDs are not consecutive.
