If we enable the memory stick block layer, use Kconfig to imply the BFQ I/O scheduler. As all memstick devices are single-queue, this is the scheduler that users want so let's be helpful and make sure it gets default-selected into a manual kernel configuration. It will still need to be enabled at runtime (usually with udev scripts).

If you say Y here, the MemoryStick layer will assume that all
|
|
cards stayed in their respective slots during the suspend. The
|
|
normal behaviour is to remove them at suspend and
|
|
redetecting them at resume. Breaking this assumption will
|
|
in most cases result in data corruption.
|
|
|
|
This option is usually just for embedded systems which use
|
|
a MemoryStick card for rootfs. Most people should say N here.

Say Y here to enable the MemoryStick Pro block device driver
|
|
support. This provides a block device driver, which you can use
|
|
to mount the filesystem. Almost everyone wishing MemoryStick
|
|
support should say Y or M here.

help
|
|
Say Y here to enable the MemoryStick Standard device driver
|
|
support. This provides a block device driver, which you can use
|
|
to mount the filesystem.
|
|
This driver works with old (bulky) MemoryStick and MemoryStick Duo
|
|
but not PRO. Say Y if you have such card.
|
|
Driver is new and not yet well tested, thus it can damage your card
|
|
(even permanently)
