[PATCH 3.16 174/366] scsi: sd: Defer spinning up drive while SANITIZE is in progress

[Ben Hutchings]

3.16.60-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Mahesh Rajashekhara <mahesh.rajashekhara@xxxxxxxxxxxxx>

commit 505aa4b6a8834a2300971c5220c380c3271ebde3 upstream.

A drive being sanitized will return NOT READY / ASC 0x4 / ASCQ
0x1b ("LOGICAL UNIT NOT READY. SANITIZE IN PROGRESS").

Prevent spinning up the drive until this condition clears.

[mkp: tweaked commit message]
