sundev1 $ echo ${BIT${SUBSET_BIT_NUM}}

trace-cmd-reset
TRACE-CMD-RESET(1) TRACE-CMD-RESET(1) NAME
trace-cmd-reset - turn off all Ftrace tracing to bring back full performance SYNOPSIS
trace-cmd reset [OPTIONS] DESCRIPTION
The trace-cmd(1) reset command turns off all tracing of Ftrace. This will bring back the performance of the system before tracing was enabled. This is necessary since trace-cmd-record(1), trace-cmd-stop(1) and trace-cmd-extract(1) do not disable the tracer, event after the data has been pulled from the buffers. The rational is that the user may want to manually enable the tracer with the Ftrace pseudo file system, or examine other parts of Ftrace to see what trace-cmd did. After the reset command happens, the data in the ring buffer, and the options that were used are all lost. OPTIONS
-b buffer_size When the kernel boots, the Ftrace ring buffer is of a minimal size (3 pages per CPU). The first time the tracer is used, the ring buffer size expands to what it was set for (default 1.4 Megs per CPU). If no more tracing is to be done, this option allows you to shrink the ring buffer down to free up available memory. trace-cmd reset -b 1 SEE ALSO
trace-cmd(1), trace-cmd-record(1), trace-cmd-report(1), trace-cmd-start(1), trace-cmd-stop(1), trace-cmd-extract(1), trace-cmd-split(1), trace-cmd-list(1), trace-cmd-listen(1) AUTHOR
