+Updating on-disk metadata
+-------------------------
+
+On-disk metadata is committed every time a FLUSH or FUA bio is written.
+If no such requests are made then commits will occur every second. This
+means the thin-provisioning target behaves like a physical disk that has
+a volatile write cache. If power is lost you may lose some recent
+writes. The metadata should always be consistent in spite of any crash.
+
+If data space is exhausted the pool will either error or queue IO
+according to the configuration (see: error_if_no_space). If metadata
+space is exhausted or a metadata operation fails: the pool will error IO
+until the pool is taken offline and repair is performed to 1) fix any
+potential inconsistencies and 2) clear the flag that imposes repair.
+Once the pool's metadata device is repaired it may be resized, which
+will allow the pool to return to normal operation. Note that if a pool
+is flagged as needing repair, the pool's data and metadata devices
+cannot be resized until repair is performed. It should also be noted
+that when the pool's metadata space is exhausted the current metadata
+transaction is aborted. Given that the pool will cache IO whose
+completion may have already been acknowledged to upper IO layers
+(e.g. filesystem) it is strongly suggested that consistency checks
+(e.g. fsck) be performed on those layers when repair of the pool is
+required.

- This driver uses ACPI INT3403 device objects. If present, it will

+ Newer laptops and tablets that use ACPI may have thermal sensors
+ outside the core CPU/SOC for thermal safety reasons. These
+ temperature sensors are also exposed for the OS to use via the so
+ called INT3403 ACPI object. This driver will, on devices that have
+ such sensors, expose the temperature information from these sensors
+ to userspace via the normal thermal framework. This means that a wide
+ range of applications and GUI widgets can show this information to
+ the user or use this information for making decisions. For example,
+ the Intel Thermal Daemon can use this information to allow the user
+ to select his laptop to run without turning on the fans.
