[lustre-devel] [PATCH 2/2] staging/lustre/ptlrpc: update imp_known_replied_xid on resend-replay

[Oleg Drokin]

From: Niu Yawei <yawei.niu at intel.com>

The imp_known_replied_xid should be updated when try to resend
an already replied replay request, because the xid of this replay
request could be less than current imp_known_replied_xid.
