2013-10-25[SCSI] qla4xxx: correctly update session discovery_parent_idx.Manish Rangankar
Earlier logic for driver created iscsi_session->discovery_parent_idx was to store ram index of a sendtarget entry, but driver frees sendtarget ram index as soon as firmware is done with discovery, which is available for further use. So changing the logic to point iscsi_session->discovery_parent_idx to store sendtarget flashnode index.

2013-07-03drivers: avoid format strings in names passed to alloc_workqueue()Kees Cook
For the workqueue creation interfaces that do not expect format strings, make sure they cannot accidently be parsed that way. Additionally, clean up calls made with a single parameter that would be handled as a format string. Many callers are passing potentially dynamic string content, so use "%s" in those cases to avoid any potential accidents.
