block: sed-opal: PSID reverttper capability
PSID is a 32 character password printed on the drive label, to prove its physical access. This PSID reverttper function is very useful to regain the control over the drive when it is locked and the user can no longer access it because of some failures. However, *all the data on the drive is completely erased*. This method is advisable only when the user is exhausted of all other recovery methods. PSID capabilities are described in: https://trustedcomputinggroup.org/wp-content/uploads/TCG_Storage-Opal_Feature_Set_PSID_v1.00_r1.00.pdf Signed-off-by: Revanth Rajashekar <revanth.rajashekar@intel.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
