Revision e8f11db956aa09c1618051a7aaf367d6810d8d8c authored by Christoph Hellwig on 29 August 2017, 12:42:06 UTC, committed by Tejun Heo on 29 August 2017, 15:33:24 UTC
ATA-8 and later mirrors the TRUSTED COMPUTING SUPPORTED bit in word 48 of
the IDENTIFY DEVICE data. Check this before issuing a READ LOG PAGE
command to avoid issues with buggy devices. The only downside is that
we can't support Security Send / Receive for a device with an older
revision due to the conflicting use of this field in earlier
specifications.
tj: The reason we need this is because some devices which don't
support READ LOG PAGE lock up after getting issued that command.
