[PATCH 0 of 4] aio event fd support to blktap2
Get blktap2 running on pvops.
This mainly adds eventfd support to the userland code. Based on some
prior cleanup to tapdisk-queue and the server object. We had most of
that in XenServer for a while, so I kept it stacked.
1. Clean up IPC and AIO init in tapdisk-server.
[I think tapdisk-ipc in blktap2 is basically obsolete.
Pending a later patch to remove it?]
2. Split tapdisk-queue into

[PATCH 0 of 6 RESEND v2] blktap3/sring: shared ring between tapdisk and the front-end
This patch series introduces the shared ring used by the front-end to pass
request descriptors to tapdisk, as well as responses from tapdisk to the
front-end. Requests from this ring end up in tapdisk''s standard request queue.
When the tapback daemon detects that the front-end tries to connect to the
back-end, it spawns a tapdisk and tells it to connect to the shared ring. The

Errors of doing "make install-tools" with xen-4.2-unstable?
Hi,
When I do the "make install-tools" with xen-4.2-unstable, there are some
errors about "warn_unused_result".
Is it the error in code or the error in the compiling environment? Thank
you so much.

[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 v2 00/12] gendisk: Generate uevent after attribute available
The race condition is noticed between disk_add() and disk attributes, on
virtio-blk hotplug.
Userspace listens to the KOBJ_ADD uevent generated in add_disk(). At that
point we haven't created the serial attribute file, therefore depending
on how fast udev reacts, the /dev/disk/by-id/ entry doesn't always get
created.
