miscdevice: Add helper macro for misc device boilerplate

2016-08-31T12:12:35Z

Many modules call misc_register and misc_deregister in its module init and exit methods without any additional code. This ends up being boilerplate. This patch adds helper macro module_misc_device(), that replaces module_init()/ module_exit() with template functions. This patch also converts drivers to use new macro. Change since v1: Add device.h include in miscdevice.h as module_driver macro was not available from other include files in some architectures.

vhost: rename vhost_init_used()

2016-03-02T15:02:04Z

Looking at how callers use this, maybe we should just rename init_used to vhost_vq_init_access. The _used suffix was a hint that we access the vq used ring. But maybe what callers care about is that it must be called after access_ok. Also, this function manipulates the vq->is_le field which isn't related to the vq used ring. This patch simply renames vhost_init_used() to vhost_vq_init_access() as suggested by Michael. No behaviour change. Signed-off-by: Greg Kurz Signed-off-by: Michael S. Tsirkin

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

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
