SUMMARY = "Generates traces of I/O traffic on block devices"
DESCRIPTION = "blktrace is a block layer IO tracing mechanism which provides \
detailed information about request queue operations up to user space. There \
are three major components: a kernel component, a utility to record the i/o \
trace information for the kernel to user space, and utilities to analyse and \
view the trace information."
