scsi: core: Handle depopulation and restoration in progress
The default handling of the NOT READY sense key is to wait for the device to become ready. 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.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
