Arguably I'd remove also the brackets around the context, they also don't convey useful information IMHO, and also would replace '.' with 'u', so it would become: + 3.00% find kernel k n_tty_write + 2.59% find kernel k _raw_spin_lock_irqsave + 2.43% find find u knuth_morris_pratt_unibyte + 2.22% sshd sshd u 41841 + 2.16% swapper kernel k mwait_idle + 1.65% find libc-2.12.so u __GI_vfprintf Something else that is missing in the tui is a header with the names of the columns, that is present in the stdio based formatter. - Arnaldo -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
