From 005a5a06a6dd13a0ca3f2c6a0218e8d94ed36d8a Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Sun, 30 Oct 2005 23:31:48 -0500 Subject: [libata] locking rewrite (== fix) A lot of power packed into a little patch. This change eliminates the sharing between our controller-wide spinlock and the SCSI core's Scsi_Host lock. As the locking in libata was already highly compartmentalized, always referencing our own lock, and never scsi_host::host_lock. As a side effect, this change eliminates a deadlock from calling scsi_finish_command() while inside our spinlock. --- drivers/scsi/libata-core.c | 2 -- 1 file changed, 2 deletions(-) (limited to 'drivers/scsi/libata-core.c') diff --git a/drivers/scsi/libata-core.c b/drivers/scsi/libata-core.c index a17e120..ff18fa7 100644 --- a/drivers/scsi/libata-core.c +++ b/drivers/scsi/libata-core.c @@ -4089,8 +4089,6 @@ static void ata_host_init(struct ata_port *ap, struct Scsi_Host *host, host->unique_id = ata_unique_id++; host->max_cmd_len = 12; - scsi_assign_lock(host, &host_set->lock); - ap->flags = ATA_FLAG_PORT_DISABLED; ap->id = host->unique_id; ap->host = host; -- cgit v1.1
