From 668108d73bbb1ae85f01db38d6be822fd28ece1f Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sun, 23 Sep 2007 13:14:13 +0900 Subject: libata-pmp-prep: implement EH fast-fail path If PMP itself becomes inaccessible while trying to link a downstream link, spending time to recover the downstream link doesn't make any sense. Make EH skip retry and fail fast if -ERESTART is received.
