+ SD/MMC is a high latency protocol where it is crucial to
|
|
|
+ send large requests in order to get high performance. Many
|
|
|
+ controllers, however, are restricted to continuous memory
|
|
|
+ (i.e. they can't do scatter-gather), something the kernel

|
+ rarely can provide.

+
|

|
+ Say Y here to help these restricted hosts by bouncing
|
