[for-next][PATCH 09/16] tracing: Clean up hist_field_flags enum

From: Tom Zanussi As we add more flags, specifying explicit integers for the flag values becomes more unwieldy and error-prone - switch them over to left-shift values. Link:

[for-next][PATCH 01/16] tracing: Remove obsolete sched_switch tracer selftest

From: Joel Fernandes Since commit 87d80de2800d087ea833cb79bc13f85ff34ed49f ("tracing: Remove obsolete sched_switch tracer"), the sched_switch tracer selftest is no longer used. This patch removes the same. Link:

[for-next][PATCH 10/16] tracing: Add hist_field_name() accessor

From: Tom Zanussi In preparation for hist_fields that won't be strictly based on trace_event_fields, add a new hist_field_name() accessor to allow that flexibility and update associated users. Link:

[for-next][PATCH 02/16] tracing: Remove redundant unread variable ret

From: Colin Ian King Integer ret is being assigned but never used and hence it is redundant. Remove it, fixes clang warning: trace_events_hist.c:1077:3: warning: Value stored to 'ret' is never read Link:

[for-next][PATCH 03/16] tracing: Reverse the order of trace_types_lock and event_mutex

From: "Steven Rostedt (VMware)" In order to make future changes where we need to call tracing_set_clock() from within an event command, the order of trace_types_lock and event_mutex must be reversed, as the event command will hold event_mutex and the trace_types_lock is

[for-next][PATCH 04/16] ring-buffer: Rewrite trace_recursive_(un)lock() to be simpler

From: "Steven Rostedt (VMware)" The current method to prevent the ring buffer from entering into a recursize loop is to use a bitmask and set the bit that maps to the current context (normal, softirq, irq or NMI), and if that bit was already set, it is considered a recursive

[PATCH] linux/types.h: Restore the ability to disable sparse endianness checks

The purpose of patch "linux/types.h: enable endian checks for all sparse builds" was to encourage driver authors to annotate endianness correctly in their drivers. However, since that patch went upstream no endianness annotations in drivers have been fixed. I think that this shows that the
