[PATCH] virtio-blk: make the queue depth configurable
Couple more bikesheddy things:
Is there ever a reason to use a non __builtin_const_p(perms)?
Maybe that should be a BUILD_BUG_ON too
BUILD_BUG_ON(!builtin_const_p_perms)
My brain of little size gets confused by the
BUILD_BUG_ON_ZERO(foo) +
vs
BUILD_BUG_ON(foo);
as it just seems like more text for the same content.
Is there any value on the "_ZERO(foo) +" I don't understand?

[PATCH 0/13 v7] PCI: Linux kernel SR-IOV support
Greetings,
Following patches are intended to support SR-IOV capability in the
Linux kernel. With these patches, people can turn a PCI device with
the capability into multiple ones from software perspective, which
will benefit KVM and achieve other purposes such as QoS, security,
and etc.
The Physical Function and Virtual Function drivers using the SR-IOV
APIs will come soon!
