+ help
+ Usually 2 buffers are enough to establish a good buffering
+ pipeline. The number may be increased in order to compensate
+ for a bursty VFS behaviour. For instance there may be CPU wake up
+ latencies that makes the VFS to appear bursty in a system with
+ an CPU on-demand governor. Especially if DMA is doing IO to
+ offload the CPU. In this case the CPU will go into power
+ save often and spin up occasionally to move data within VFS.
+ If selecting USB_GADGET_DEBUG_FILES this value may be set by
+ a module parameter as well.
+ If unsure, say 2.
