[SCSI] scsi_dh: add infrastructure for SCSI Device Handlers Some of the storage devices (that can be accessed through multiple paths), do need some special handling for 1. Activating the passive path of the storage access. 2. Decode and handle the special sense codes returned by the devices. 3. Handle the I/Os being sent to the passive path, especially during the device probe time. when accessed through multiple paths. As of today this special device handling is done at the dm-multipath layer using dm-handlers. That works well for (1); for (2) to be handled at dm layer, scsi sense information need to be exported from SCSI to dm-layer, which is not very attractive; (3) cannot be done at all at the dm layer. Device handler has been moved to SCSI mainly to handle (2) and (3) properly.

scsi_dh: integrate into the core SCSI code Stop building scsi_dh as a separate module and integrate it fully into the core SCSI code with explicit callouts at bus scan time. For now the callouts are placed at the same point as the old bus notifiers were called, but in the future we will be able to look at ALUA INQUIRY data earlier on. Note that this also means that the device handler modules need to be loaded by the time we scan the bus. The next patches will add support for autoloading device handlers at bus scan time to make sure they are always loaded if they are enabled in the kernel config.
