The "wait" is assumed to be relatively short. However there is a sub-class of NOT READY that have the "... in progress" phrase in their additional sense code and these can take much longer. Following on from commit 505aa4b6a883 ("scsi: sd: Defer spinning up drive while SANITIZE is in progress") we now have element depopulation and restoration that can take a long time. For example, over 24 hours for a 20 TB, 7200 rpm hard disk to depopulate 1 of its 20 elements. Add handling of ASC/ASCQ: 0x4,0x24 (depopulation in progress) and ASC/ASCQ: 0x4,0x25 (depopulation restoration in progress) to sd.c . The scsi_lib.c has incomplete handling of these two messages, so complete it.
