From 8d8e7d13146eb6be8b98dbd58ac30421a4f8edf3 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Mon, 9 Jul 2012 21:06:08 -0700 Subject: [PATCH] [SCSI] libsas, ipr: cleanup ata_host flags initialization via ata_host_init libsas and ipr pass flags to ata_host_init that are meant for the port. ata_host flags: ATA_HOST_SIMPLEX = (1 << 0), /* Host is simplex, one DMA channel per host only */ ATA_HOST_STARTED = (1 << 1), /* Host started */ ATA_HOST_PARALLEL_SCAN = (1 << 2), /* Ports on this host can be scanned in parallel */ ATA_HOST_IGNORE_ATA = (1 << 3), /* Ignore ATA devices on this host. */ flags passed by libsas: ATA_FLAG_SATA = (1 << 1), ATA_FLAG_PIO_DMA = (1 << 7), /* PIO cmds via DMA */ ATA_FLAG_NCQ = (1 << 10), /* host supports NCQ */ The only one that aliases is ATA_HOST_STARTED which is a 'don't care' in the libsas and ipr cases since ata_hosts from these sources are not registered with libata.
