From: Arnaldo Carvalho de Melo Date: Fri, 14 Jul 2017 18:16:54 +0000 (-0300) Subject: perf trace beauty: Give syscall return beautifier more context X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7ee5743404e3641f3c11792761632a5a7d583587;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git perf trace beauty: Give syscall return beautifier more context We need the current thread and the trace internal state so that we can use the fd beautifier to augment syscall returns, so use struct syscall_arg with some fields that make sense on returns (val, thread, trace).
