The btrace script provides a quick and easy way to do live tracing of
block devices. It calls blktrace on the specified devices and pipes
the output through blkparse for formatting. See blktrace (8) for
more in-depth information about how blktrace works.
-s Displays data sorted by program (see blkparse (1)).
-t Displays time deltas per IO (see blkparse (1)).
-w N Sets run time to the number of seconds specified (see blktrace
-n N Specifies the number of buffers to use (see blktrace (8)).
-b N Specifies buffer size for event extraction (scaled by 1024) (see
-r <dbg mnt> Specifies the debugfs mountpoint.
-a <trace>... Adds mask to current filter (see blktrace (8)).
<dev> Specifies the device to trace.
