* git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6: (182 commits) [SCSI] aacraid: add an ifdef'd device delete case instead of taking the device offline [SCSI] aacraid: prohibit access to array container space [SCSI] aacraid: add support for handling ATA pass-through commands. [SCSI] aacraid: expose physical devices for models with newer firmware [SCSI] aacraid: respond automatically to volumes added by config tool [SCSI] fcoe: fix fcoe module ref counting [SCSI] libfcoe: FIP Keep-Alive messages for VPorts are sent with incorrect port_id and wwn [SCSI] libfcoe: Fix incorrect MAC address clearing [SCSI] fcoe: fix a circular locking issue with rtnl and sysfs mutex [SCSI] libfc: Move the port_id into lport [SCSI] fcoe: move link speed checking into its own routine [SCSI] libfc: Remove extra pointer check [SCSI] libfc: Remove unused fc_get_host_port_type [SCSI] fcoe: fixes wrong error exit in fcoe_create [SCSI] libfc: set seq_id for incoming sequence [SCSI] qla2xxx: Updates to ISP82xx support. [SCSI] qla2xxx: Optionally disable target reset. [SCSI] qla2xxx: ensure flash operation and host reset via sg_reset are mutually exclusive [SCSI] qla2xxx: Silence bogus warning by gcc for wrap and did. [SCSI] qla2xxx: T10 DIF support added. ...
