vhost: make features 64 bit

2014-12-09T10:05:28Z

We need to use bit 32 for virtio 1.0. Make vhost_has_feature bool to avoid discarding high bits. Cc: Sergei Shtylyov Cc: Ben Hutchings Signed-off-by: Michael S. Tsirkin Reviewed-by: Jason Wang

vhost: move memory pointer to VQs

2014-06-09T13:21:07Z

commit 2ae76693b8bcabf370b981cd00c36cd41d33fabc vhost: replace rcu with mutex replaced rcu sync for memory accesses with VQ mutex locl/unlock. This is correct since all accesses are under VQ mutex, but incomplete: we still do useless rcu lock/unlock operations, someone might copy this code into some other context where this won't be right. This use of RCU is also non standard and hard to understand. Let's copy the pointer to each VQ structure, this way the access rules become straight-forward, and there's no need for RCU anymore.

vhost: move acked_features to VQs

2014-06-09T13:21:06Z

Refactor code to make sure features are only accessed under VQ mutex. This makes everything simpler, no need for RCU here anymore. Signed-off-by: Michael S. Tsirkin

vhost: remove the dead branch

2013-12-06T20:22:05Z

Since vhost_dev_init() forever return 0, some branches are never run, therefore need to be removed. Signed-off-by: Zhi Yong Wu Acked-by: Michael S. Tsirkin Signed-off-by: David S. Miller

vhost: Remove custom vhost rcu usage

2013-07-11T12:38:40Z

Now, vq->private_data is always accessed under vq mutex. No need to play the vhost rcu trick. Signed-off-by: Asias He Signed-off-by: Michael S. Tsirkin

vhost: Make vhost a separate module

2013-07-07T14:33:44Z

Currently, vhost-net and vhost-scsi are sharing the vhost core code. However, vhost-scsi shares the code by including the vhost.c file directly. Making vhost a separate module makes it is easier to share code with other vhost devices. Signed-off-by: Asias He Signed-off-by: Michael S. Tsirkin

vhost: check owner before we overwrite ubuf_info

2013-06-11T09:46:21Z

If device has an owner, we shouldn't touch ubuf_info since it might be in use. Signed-off-by: Michael S. Tsirkin Signed-off-by: David S. Miller

vhost: Remove vhost_enable_zcopy in vhost.h
