Subject: scsi: sd: Defer spinning up drive while SANITIZE is in progress
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b23b4174275d397281023703ce19ff793e6dfd98;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

scsi: sd: Defer spinning up drive while SANITIZE is in progress

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]
