Thanks, applied. I'm thinking about making --no-syscalls the default when 'trace' is hardlinked to 'perf', i.e. 'perf trace' remains as it is, but if one calls 'trace', then --no-syscalls is the default, as after non-syscall events got supported I find myself using --no-syscalls way too often, what do you think? Or perhaps have a 'perf strace' to try to have as much in common with 'strace' in terms of default behaviour, options, etc? - Arnaldo > Signed-off-by: Ravi Bangoria <ravi.bango...@linux.vnet.ibm.com> > --- > tools/perf/Documentation/perf-trace.txt | 3 ++- > 1 file changed, 2 insertions(+), 1 deletion(-) > > diff --git a/tools/perf/Documentation/perf-trace.txt > b/tools/perf/Documentation/perf-trace.txt > index afd7286..c1e3288 100644 > --- a/tools/perf/Documentation/perf-trace.txt > +++ b/tools/perf/Documentation/perf-trace.txt > @@ -123,7 +123,8 @@ the thread executes on the designated CPUs.
