This patchset addresses several issues in connection (graceful/ungraceful) teardown. Patch #1 addresses a possible np_thread hang when isert_accept_np retook isert_np semaphore and never left it. Patch #2 addresses connection teardown hang when isert_wait_conn had waited for iser disconnected handler that never arrived. Patch #3 addresses other RDMA_CM events that were not properly handled. Patch #4 makes sure that ib_isert unload will properly cleanup before finishing. This patchset survived several nights of: - Unstable link (cable pull of both initiator and target ports). - stack unload during live IO and unstable link. Slava will continue iSER target qualification efforts (Thanks Slava!).
