3860c97bd6 [SCSI] osd: Remove out-of-tree left overs
* Delete Makefile. It is only used for out-of-tree compilation
  and was never needed. It slipped in by mistake.
* Remove from Kbuild all the out of tree stuff as promised.

98f3aea2bd [SCSI] libosd: SCSI/OSD Sense decoding support
Implementation of the osd_req_decode_sense() API. Can be called by
library users to decode what failed in command executions.

Add SCSI_OSD_DPRINT_SENSE Kconfig variable. Possible values are:
0 - Do not print any errors to messages file <KERN_ERR>
1 - (Default) Print only decoded errors that are not recoverable.
    Recoverable errors are those that the target has complied with
    the request but with a warning. For example read passed end of
    object will return zeros after the last valid byte.
2- Print all errors.

95b05a7db5 [SCSI] osd_uld: OSD scsi ULD
Add a Linux driver module that registers as a SCSI ULD and probes
for OSD type SCSI devices.

When an OSD-type SCSI device is found a character device is created
in the form of /dev/osdX - where X goes from 0 up to hard coded 64.
The Major character device number used is 260.
