perf diff: Change the default sort order to "dso,symbol"
This is a more intuitive / more meaningful default: $ perf diff | head -8 9.02% +1.00% libc-2.10.1.so [.] _IO_vfprintf_internal 2.91% -1.00% [kernel] [k] __kmalloc 2.85% -1.00% [kernel] [k] ext4_htree_store_dirent 1.99% -1.00% [kernel] [k] _atomic_dec_and_lock 2.44% [kernel] $ Suggested-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Frédéric Weisbecker <fweisbec@gmail.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Paul Mackerras <paulus@samba.org> LKML-Reference: <1260979793-1981-1-git-send-email-acme@infradead.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
