 Inline encryption support
 =========================
 
-By default, fscrypt uses the kernel crypto API for all cryptographic
-operations (other than HKDF, which fscrypt partially implements
-itself).  The kernel crypto API supports hardware crypto accelerators,
-but only ones that work in the traditional way where all inputs and
-outputs (e.g. plaintexts and ciphertexts) are in memory.  fscrypt can
-take advantage of such hardware, but the traditional acceleration
-model isn't particularly efficient and fscrypt hasn't been optimized
-for it.
-
-Instead, many newer systems (especially mobile SoCs) have *inline
-encryption hardware* that can encrypt/decrypt data while it is on its
-way to/from the storage device.  Linux supports inline encryption
-through a set of extensions to the block layer called *blk-crypto*.
-blk-crypto allows filesystems to attach encryption contexts to bios

 	  Select the Default SATA Link Power Management (LPM) policy to use
 	  for chipsets / "South Bridges" supporting low-power modes. Such
 	  chipsets are ubiquitous across laptops, desktops and servers.
-
-	  The value set has the following meanings:
+	  Each policy combines power saving states and features:
+	   - Partial: The Phy logic is powered but is in a reduced power
+                      state. The exit latency from this state is no longer than
+                      10us).
+	   - Slumber: The Phy logic is powered but is in an even lower power
+                      state. The exit latency from this state is potentially
+		      longer, but no longer than 10ms.
+	   - DevSleep: The Phy logic may be powered down. The exit latency from
+	               this state is no longer than 20 ms, unless otherwise
+		       specified by DETO in the device Identify Device Data log.
+	   - HIPM: Host Initiated Power Management (host automatically
+		   transitions to partial and slumber).
+	   - DIPM: Device Initiated Power Management (device automatically
+		   transitions to partial and slumber).
+
+	  The possible values for the default SATA link power management
+	  policies are:
 		0 => Keep firmware settings
-		1 => Maximum performance
-		2 => Medium power
-		3 => Medium power with Device Initiated PM enabled
-		4 => Minimum power
-
-	  Note "Minimum power" is known to cause issues, including disk
-	  corruption, with some disks and should not be used.
+		1 => No power savings (maximum performance)
+		2 => HIPM (Partial)
+		3 => HIPM (Partial) and DIPM (Partial and Slumber)
+		4 => HIPM (Partial and DevSleep) and DIPM (Partial and Slumber)
+		5 => HIPM (Slumber and DevSleep) and DIPM (Partial and Slumber)
+
+	  Excluding the value 0, higher values represent policies with higher
+	  power savings.
