Just noticed that scsi-misc was rebased since last checked.   Patch kit
re-flowed (none of the contents changed).  'libsas' is now at commit
5c41dc3:

The following changes since commit 5c41dc3a79150e93e5d050871a10b761be8281a1:

  [SCSI] lpfc 8.3.28: Update driver version to 8.3.28 (2011-12-15 10:57:45 +0400)
