[PATCH 0/2] [GIT PULL] tracing: Minor fixes

[Steven Rostedt]

Linus,

Some of the files in the tracing directory show file mode 0444
when they are writable by root. To fix the confusion, they should
be 0644. Note, either case root can still write to them.

Note, Zhengyuan asked why I never applied that patch (the first one
is from 2014!). I simply forgot about it. /me lowers head in shame.

[PATCH 1/2] ftrace: Have set_graph_* files have normal file modes

[Steven Rostedt]

[-- Attachment #1: 0001-ftrace-Have-set_graph_-files-have-normal-file-modes.patch --]
[-- Type: text/plain, Size: 1284 bytes --]

From: Chen LinX <linx.z.chen@intel.com>

The set_graph_function and set_graph_notrace file mode should be 0644
instead of 0444 as they are writeable. Note, the mode appears to be ignored
regardless, but they should at least look sane.

[PATCH 2/2] tracing: Fix the file mode of stack tracer

[Steven Rostedt]

[-- Attachment #1: 0002-tracing-Fix-the-file-mode-of-stack-tracer.patch --]
[-- Type: text/plain, Size: 956 bytes --]

From: Zhengyuan Liu <liuzhengyuan@kylinos.cn>

It looks weird that the stack_trace_filter file can be written by root
but shows that it does not have write permission by ll command.
