[PATCH 27/31] staging: lustre: ptlrpc: request gets stuck in UNREGISTERING phase

Show all headers | View raw

From: Andriy Skulysh <Andriy_Skulysh@xyratex.com>

Exit condition from UNREGISTERING phase is releasing of
both reply and bulk buffers.

Call ptlrpc_unregister_bulk() if ptlrpc_unregister_reply()
wasn't completed in async mode before switching to
UNREGISTERING phase.
