From 9508a66f898d46e726a318469312b45e0b1d078b Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Wed, 18 Jan 2012 20:47:01 -0800 Subject: [SCSI] libsas: async ata scanning libsas ata error handling is already async but this does not help the scan case. Move initial link recovery out from under host->scan_mutex, and delay synchronization with eh until after all port probe/recovery work has been queued. Device ordering is maintained with scan order by still calling sas_rphy_add() in order of domain discovery. Since we now scan the domain list when invoking libata-eh we need to be careful to check for fully initialized ata ports.
