Merge master.kernel.org:/pub/scm/linux/kernel/git/jejb/scsi-rc-fixes-2.6
* master.kernel.org:/pub/scm/linux/kernel/git/jejb/scsi-rc-fixes-2.6: (679 commits) commit 7676f83aeb774e7a3abe6af06ec92b29488b5b79 Author: James Bottomley <James.Bottomley@steeleye.com> Date: Fri Apr 14 09:47:59 2006 -0500 [SCSI] scsi_transport_sas: don't scan a non-existent end device Any end device that can't support any of the scanning protocols shouldn't be scanned, so set its id to -1 to prevent scsi_scan_target() being called for it. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com> commit 3c0c25b97c7d020ef07f6366cf1d668a8e980c7c Author: Moore, Eric <Eric.Moore@lsil.com> Date: Thu Apr 13 16:08:17 2006 -0600 [SCSI] mptfusion - fix panic in mptsas_slave_configure Driver panic when RAID logical volume was present when driver loaded, or when a RAID logical volume was created on the fly. ...
