In my machine, it has a SATA disk that supports FUA feature. But after system starts up, it displays that the disk cannot support FUA from dmesg. I notice this commit (c3c013a2). It disables FUA support in all of SATA disk. But the commit log is too simple to know why we should disable FUA support in libata. Could you please explain it? Thank you. Regards, Zheng
