[PATCH] xen-blk: persistent-grants fixes
This patch contains fixes for persistent grants implementation v2:
* handle == 0 is a valid handle, so initialize grants in blkback
setting the handle to BLKBACK_INVALID_HANDLE instead of 0. Reported
by Konrad Rzeszutek Wilk.
* new_map is a boolean, use "true" or "false" instead of 1 and 0.

What went in Linux 3.5 from Xen standpoint.
Hey,
Linus released this Saturday v3.5 and there were quite a few
of interesting components/fixes/features that went in!
Going to go down the list of what shortlog provided:
- Less MSR traps when using AMD machines - so better performance. [andre]
- The APIC IPI interface works - which means that ''perf'' in the initial
domain works. So no more lockups. Also with some

[PATCH] xen-blk[front|back] FUA additions.
I am proposing these two patches for 3.2. They allow the backend
to process the REQ_FUA request as well. Previous to these patches
it only did REQ_FLUSH. There is also a bug-fix for the logic
of how barrier/flushes were handled.
The patches are based on a branch which also has ''feature-discard''
patches, so they won''t apply nativly on top of 3.1-rc5.

[PATCH] blkback: Fix block I/O latency issue
In blkback driver, after I/O requests are submitted to Dom-0 block I/O subsystem, blkback goes to ''sleep'' effectively without letting blkfront know about it (req_event isn''t set appropriately). Hence blkfront doesn''t notify blkback when it submits a new I/O thus delaying the ''dispatch'' of the new I/O to Dom-0 block I/O subsystem. The new I/O is

[PATCH V4 0/3] xen-blkfront/blkback discard support
Dear list,
This is the V4 of the trim support for xen-blkfront/blkback,
Now we move BLKIF_OP_TRIM to BLKIF_OP_DISCARD, and dropped all
"trim" stuffs in the patches, and use "discard" instead.
Also we updated the helpers of blkif_x86_{32|64}_request or we
will meet problems using a non-native protocol.
And this patch has been tested with both SSD and raw file,

[PATCH] Persistent grant maps for xen blk drivers
This patch implements persistent grants for the xen-blk{front,back}
mechanism. The effect of this change is to reduce the number of unmap
operations performed, since they cause a (costly) TLB shootdown. This
allows the I/O performance to scale better when a large number of VMs
are performing I/O.
Previously, the blkfront driver was supplied a bvec[] from the request
queue. This was granted to

[PATCH 3/4] xen-blkback: check the number of iovecs before allocating a bios
With the introduction of indirect segments we can receive requests
with a number of segments bigger than the maximum number of allowed
iovecs in a bios, so make sure that blkback doesn't try to allocate a
bios with more iovecs than BIO_MAX_PAGES

[PATCH] xen-blk(front|back): Handle large physical sector disks
I accidentally realized today that any domU''s using the paravirt disk driver
potentially suffer from poor performance when they get handed in a physical
volume and partitioning is done inside the guest. The physical volume passed in
has to be one that has the compat 512 logical sector size but hints its real
sector size (eg. 4096) as physical sector size.
In dom0 handling is correct and

Re: Bug#637234: linux-image-3.0.0-1-686-pae: I/O errors using ext4 under xen
Hi Konrad,
Does this look at all familiar? There is some more info in the full bug
log at http://bugs.debian.org/637234 . In particular, contrary to the
message below, the user subsequently confirmed that the issue appears to
be Xen specific (doesn''t happen on native or vmware) and that it arose
between 2.6.39-2-686-pae and 3.0.0-1-686-pae.
Could it be related to edf6ef59ec7e

LVM Checksum error when using persistent grants (#linux-next + stable/for-jens-3.8)
Hey Roger,
I am seeing this weird behavior when using #linux-next + stable/for-jens-3.8 tree.
Basically I can do ''pvscan'' on xvd* disk and quite often I get checksum errors:
