56 Say Y here if you want to be able to trace the block layer actions
57 on a given queue. Tracing allows you to see any traffic happening
58 on a block device queue. For more information (and the userspace
59 support tools needed), fetch the blktrace tools from:
60
61 git://git.kernel.dk/blktrace.git
62
63 Tracing also is possible using the ftrace interface, e.g.:
64
65 echo 1 > /sys/block/sda/sda1/trace/enable
66 echo blk > /sys/kernel/debug/tracing/current_tracer
67 cat /sys/kernel/debug/tracing/trace_pipe
