Compilation warning on Utopic

[Luis Henriques]

[Impact]

When compiling the Utopic kernel, the following warning can is shown:

/tmp/kernel-henrix-EluZkimP/build/fs/exec.c: In function 'do_open_exec':
/tmp/kernel-henrix-EluZkimP/build/fs/exec.c:780:18: warning: passing argument 1 of 'trace_open_exec' from incompatible pointer type
  trace_open_exec(name);
                  ^
In file included from /tmp/kernel-henrix-EluZkimP/build/include/trace/syscall.h:4:0,

                 from /tmp/kernel-henrix-EluZkimP/build/fs/exec.c:48:

  ^
/tmp/kernel-henrix-EluZkimP/build/include/trace/events/fs.h:32:1: note: in expansion of macro 'TRACE_EVENT'
 TRACE_EVENT(open_exec,
 ^

This is due to a wrong parameter type being used while invoking trace_open_exec()

[Test Case]

A simple compilation of the kernel shows this warning.

[Fix]

A patch with the following should fix it:

- trace_open_exec(name);
+ trace_open_exec(name->name);

[Luis Henriques (henrix)]

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-utopic' to 'verification-done-utopic'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

[Luis Henriques (henrix)]

I've verified that the build logs for the utopic kernel in -proposed (3.16.0-39.53) do not have the warning in this bug description. Tagging as verified.

This bug was fixed in the package linux - 3.16.0-39.53
