Staging: hv: netvsc: Increase the timeout value in the netvsc driver

2011-08-05T04:58:32+00:00

commit 5c5781b3f88567211ecaaada13431af15c8c6003 upstream. On some loaded windows hosts, we have discovered that the host may not respond to guest requests within the specified time (one second) as evidenced by the guest timing out. Fix this problem by increasing the timeout to 5 seconds. It may be useful to apply this patch to the 3.0 kernel as well. Signed-off-by: K. Y.

Staging: hv: vmbus_drv: Get rid of util synchronixation based on channel counting

2011-05-17T20:36:50+00:00

Now that we have dealt with this issue differently, get rid of the old mechanism. Signed-off-by: K. Y. Srinivasan Signed-off-by: Haiyang Zhang Signed-off-by: Abhishek Kane Signed-off-by: Hank Janssen Signed-off-by: Greg Kroah-Hartman

Staging: hv: Re-implement the synchronization for util channels

2011-05-17T20:36:50+00:00

The util module expects that the util channels are fully initialized when the module loads. To deal with the race condition which can result in a NULL pointer dereferencing if the util module were to load before all the util channels are fully initialized, in commit: commit: 8b5d6d3bd3e34e4cc67d875c8c88007c1c9aa96 Author: Haiyang Zhang Date: Fri May 28 23:22:44 2010 +000 code was introduced in the vmbus driver to ensure that all the util channels were fully initialized before returning from the load of the vmbus driver. This solution has several problems: if for whatever reason, any util channel were to fail to initialize, vmbus driver would wait indefinitely. We deal with this synchronization issue very differently in this patch. Signed-off-by: K. Y.
