[PATCH] virtio-blk: allow toggling host cache between writeback and writethrough
...userspace API
after all, and you see to prefer writeback in one word in your own
code so let's not inflict pain on others :)
Also, would be nice to make it discoverable what the legal
values are. Another attribute valid_cache_types with all values
space separated?

[PATCH 0/7] virtio cleanups
Aiming these for coming merge window.
Nothing should change, but get ready for a non-guest-endian config transports,

Final one is just an overdue consolidation.

[PATCH 00/15] Fix issue with KOBJ_ADD uevent versus disk attributes
This is an attempt to fix the issue that some disks' sysfs attributes are not
ready at the time its KOBJ_ADD event is sent.
The symptom is during device hotplug, udev may fail to find certain attributes,
such as serial or wwn, of the disk. As a result the /dev/disk/by-id entries are
not created.
The cause is device_add_disk emits the uevent before returning, and the callers
have to create

[PATCH 00/22] New virtio PCI layout
I've renewed this again, with some comments from HPA. I've tried to
keep the new patches separate, so you can see the changes since we
last discussed this (and so it's easy to back it out if we decide it's
insane).
I haven't even looked at the QEMU side so this is completely untested.
Comments gratefully received!
Rusty.
