Nope, my patch only enables ATA_DFLAG_LOCK_SECTORS for devices flagged with SIL_QUIRK_MOD15WRITE:
{ "ST320012AS", SIL_QUIRK_MOD15WRITE }, { "ST330013AS", SIL_QUIRK_MOD15WRITE }, { "ST340017AS", SIL_QUIRK_MOD15WRITE }, { "ST360015AS", SIL_QUIRK_MOD15WRITE }, { "ST380023AS", SIL_QUIRK_MOD15WRITE }, { "ST3120023AS", SIL_QUIRK_MOD15WRITE }, { "ST340014ASL", SIL_QUIRK_MOD15WRITE }, { "ST360014ASL", SIL_QUIRK_MOD15WRITE }, { "ST380011ASL", SIL_QUIRK_MOD15WRITE }, { "ST3120022ASL", SIL_QUIRK_MOD15WRITE }, { "ST3160021ASL", SIL_QUIRK_MOD15WRITE }, { "Maxtor 4D060H3", SIL_QUIRK_UDMA5MAX }, [...] if (quirks & SIL_QUIRK_MOD15WRITE) { printk(KERN_INFO "ata%u(%u): applying errata fix\n", ap->id, dev->devno); ap->host->max_sectors = 15; ap->host->hostt->max_sectors = 15; dev->flags |= ATA_DFLAG_LOCK_SECTORS; return; } - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
