From 91895b786e631ab47b618c901231f22b5a44115b Mon Sep 17 00:00:00 2001 From: Zheng Liu Date: Tue, 8 May 2012 11:24:03 +0800 Subject: [PATCH] libata: enable SATA disk fua detection on default Currently, SATA disk fua detection is disabled on default because most of devices don't support this feature at that time. With the development of technology, more and more SATA disks support this feature. So now we can enable this detection on default. Although fua detection is defined as a kernel module parameter, it is too hard to set its value because it must be loaded and set before system starts up. That needs to modify initrd file. So it is inconvenient for administrator who needs to manage a huge number of servers.
