From: Steven Rostedt Date: Fri, 1 Jun 2012 01:28:58 +0000 (-0400) Subject: tracing: Add comments for the other bits of ftrace_event_call.flags X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5da43bed800770906fca24deef7ae3d456823b86;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git tracing: Add comments for the other bits of ftrace_event_call.flags TRACE_EVENT_FL_ENABLED_BIT, TRACE_EVENT_FL_FILTERED_BIT, TRACE_EVENT_FL_RECORDED_CMD_BIT, Have comments about what they are, but: TRACE_EVENT_FL_CAP_ANY_BIT, TRACE_EVENT_FL_NO_SET_FILTER_BIT, TRACE_EVENT_FL_IGNORE_ENABLE_BIT, do not, making them second class citizens. To prevent another class warfare, these bits have protested for their right to be commented. And By Golly! I'll give them what they want!
