v4: - Resending v3 after reviewer feedback (Shuah Khan). - No code changes. - Fixes email formatting and broken threading in earlier versions.

v3: - Rebased against upstream seccomp tree. - Fixed indentation to use tabs instead of spaces. - Used scripts/checkpatch.pl to fix warnings. - Removed blank line before Signed-off-by.

v2: - Used TH_LOG instead of printf for error logging. - Moved variable declaration to the top of the function. - Applied review suggestions from Kees Cook.

v1: - Initial patch to improve error logging in get_proc_stat().
