Component Type: kbuild config

Description: Support for tracing block IO actions

More info: Say Y here if you want to be able to trace the block layer actions on a given queue. Tracing allows you to see any traffic happening on a block device queue. For more information (and the userspace support tools needed), fetch the blktrace tools from: git://git.kernel.dk/blktrace.git Tracing also is possible using the ftrace interface, e.g.: echo 1 > /sys/block/sda/sda1/trace/enable echo blk > /sys/kernel/debug/tracing/current_tracer cat /sys/kernel/debug/tracing/trace_pipe If unsure, say N.
