		This is the smallest unit a physical storage device can

		write atomically.  It is usually the same as the logical

		block size but may be bigger.  One example is SATA

		drives with 4KB sectors that expose a 512-byte logical

		block size to the operating system.  For stacked block

What:		/sys/block/<disk>/queue/minimum_io_size

Contact:	Martin K. Petersen <martin.petersen@oracle.com>

Description:

		Storage devices may report a preferred minimum I/O size,

		which is the smallest request the device can perform

		without incurring a read-modify-write penalty.  For disk

		drives this is often the physical block size.  For RAID

		arrays it is often the stripe chunk size.

		Storage devices may report a granularity or preferred

		minimum I/O size which is the smallest request the

		device can perform without incurring a performance

		penalty.  For disk drives this is often the physical

		block size.  For RAID arrays it is often the stripe

		chunk size.  A properly aligned multiple of

		minimum_io_size is the preferred request size for

		workloads where a high number of I/O operations is

		desired.

Description:

		Storage devices may report an optimal I/O size, which is

What:		/sys/bus/pci/devices/.../reset

Date:		July 2009

Contact:	Michael S. Tsirkin <mst@redhat.com>

Description:

		Some devices allow an individual function to be reset

		without affecting other functions in the same device.

		For devices that have this support, a file named reset

		will be present in sysfs.  Writing 1 to this file

		will perform reset.
