[PATCH v2 05/14] RDS: defer the over_batch work to send worker

From: Santosh Shilimkar
Date: Wed Sep 30 2015 - 13:32:10 EST

Current process gives up if its send work over the batch limit.
The work queue will get kicked to finish off any other requests.
This fixes remainder condition from commit 443be0e5affe ("RDS: make
sure not to loop forever inside rds_send_xmit").

The restart condition is only for the case where we reached to
over_batch code for some other reason so just retrying again
before giving up.
