[PATCH v3 0/8] vdpa_sim: add support for user VA
This series adds support for the use of user virtual addresses in the
vDPA simulator devices.
The main reason for this change is to lift the pinning of all guest memory.
Especially with virtio devices implemented in software.
The next step would be to generalize the code in vdpa-sim to allow the
implementation of in-kernel software devices. Similar to vhost, but using vDPA
so we can reuse the

[PATCH v2 0/8] vdpa_sim: add support for user VA
v2:
- rebased on Linus' tree, commit ae3419fbac84 ("vc_screen: don't clobber
return value in vcs_read")
- removed `struct task_struct *owner` param (unused for now, maybe
?useful to support cgroups) [Jason]
- add unbind_mm callback [Jason]
- call the new unbind_mm callback during the release [Jason]
- avoid to call bind_mm callback after the reset, since the device

[PATCH v2 0/2] vhost-scsi: Fix IO hangs when using windows
The following patches were made over Linus's tree and fix an issue
where windows guests will send iovecs with offset/lengths that result
in IOs that are not aligned to 512. The LIO layer will then send them
to Linux's FS/block layer but it requires 512 byte alignment, so
depending on the FS/block driver being used we will get IO errors or
hung IO.
The following patches have vhost-scsi
