From 6a719391e4a13d5fa2ec7642ef0c780d7f3f5716 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Thu, 8 Dec 2011 00:37:25 -0800 Subject: [SCSI] isci: remove bus and reset handlers Remove ->eh_device_reset_handler() and ->eh_bus_reset_handler() for the same reason they are not implemented for libata hosts, they cannot be implemented reliably with ata-eh. ATA error recovery wants to divert all resets to the eh thread and wait for completion, these handlers may be invoked from a non-blocking ioctl. The other path they are called from is libsas-eh, and if we escalate past I_T_nexus reset we have larger problems i.e. tear down all in-flight commands in the domain potentially without notification to the lldd if it has chosen not to implement ->lldd_clear_nexus_port() / ->lldd_clear_nexus_ha().
