2011-10-19net: add skb frag size accessorsEric Dumazet
To ease skb->truesize sanitization, its better to be able to localize all references to skb frags size.

2011-10-10Staging: hv: move hyperv code out of staging directoryGreg Kroah-Hartman
After many years wandering the desert, it is finally time for the Microsoft HyperV code to move out of the staging directory.

2011-10-10Staging: hv: util: Invoke cn_netlink_send() in a work contextK. Y. Srinivasan
Invoke cn_netlink_send() in a work context as opposed being called in the context of channel callback. On entry into the channel callback code the channel inbound spin lock is held and deferring to a work context avoids having to invoke cn_netlink_send() while holding the inbound lock. As part of this adjustment, also increase the timeout value for waiting for the user level component of KVP. Signed-off-by: K. Y.

2011-10-10Staging: hv: util: Fix a bug in kvp implementationK. Y. Srinivasan
The host gurantees that there can be only one kvp transaction active against the guest. So, the transaction active state is needed only to protect against spurious user level calls. The current code had a race condition where the guest could prematurely return because the previous transaction state was not cleared - this state was being cleared after sending the response to the host and there was a window where the host could notify the guest of a new transaction before the transaction active state was properly set. Also deal with the case when the user mode component does not respond in a timely fashion correctly. I would like to thank Long Li <longli@microsoft.com> for identifying the problem.
