From c78bb8442b14ee6704bdb323111ffa874d4bfdaa Mon Sep 17 00:00:00 2001 From: Krishna Kumar Date: Fri, 24 Nov 2006 16:02:34 +0530 Subject: RDMA/addr: Fix some cancellation problems in process_req() Fix following problems in process_req() relating to cancellation: - Function is wrongly doing another addr_remote() when cancelled, which is not required. - Make failure reporting immediate by using time_after_eq(). - On cancellation, -ETIMEDOUT was returned to the callback routine instead of the more appropriate -ECANCELLED (users getting notified may want to print/return this status, eg ucma_event_handler).
