[lustre-devel] [PATCH 27/45] lustre: ptlrpc: connect to MDT stucks

[James Simmons]

From: Andriy Skulysh <c17819 at cray.com>

mdc_ioc_hsm_ct_register() is executed on
IMP_EVENT_ACTIVE event.
If HSM_CT_REGISTER request expires import becomes
disconnected but reconnect can't start because
previous connect waits for completion of
HSM_CT_REGISTER request.

Mark HSM_CT_REGISTER request as no_resend.
