From: Andi Kleen Date: Fri, 20 Sep 2013 14:40:43 +0000 (-0700) Subject: tools/perf: Add support for record transaction flags X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=475eeab9f3c1579c8da89667496084db4867bf7c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git tools/perf: Add support for record transaction flags Add support for recording and displaying the transaction flags. They are essentially a new sort key. Also display them in a nice way to the user.
