New Revision: 41752
URL: http://svn.reactos.org/svn/reactos?rev=41752&view=rev
Log:
- TCPIP lock rewrite (part 3 of 3)
- Use a spin lock to protect the signalled connections list
- Add a debug ASSERT into each function that depends on the TCPLock being held
- Release TCPLock before completing the IRP
- Add some locking where it was forgotten
- Optimize HandleSignalledConnection
