From cca3974e48607c3775dc73b544a5700b2e37c21a Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Thu, 24 Aug 2006 03:19:22 -0400 Subject: libata: Grand renaming. The biggest change is that ata_host_set is renamed to ata_host. * ata_host_set => ata_host * ata_probe_ent->host_flags => ata_probe_ent->port_flags * ata_probe_ent->host_set_flags => ata_probe_ent->_host_flags * ata_host_stats => ata_port_stats * ata_port->host => ata_port->scsi_host * ata_port->host_set => ata_port->host * ata_port_info->host_flags => ata_port_info->flags * ata_(.*)host_set(.*)\(\) => ata_\1host\2() The leading underscore in ata_probe_ent->_host_flags is to avoid reusing ->host_flags for different purpose. Currently, the only user of the field is libata-bmdma.c and probe_ent itself is scheduled to be removed. ata_port->host is reused for different purpose but this field is used inside libata core proper and of different type.
