Use TH_LOG to report failure when reading /proc/<pid>/stat in get_proc_stat(), following kernel test framework conventions.
Previously, printf() was used which is discouraged.
printf wasn't used previous, that was in your v1. :)

No blank line here -- other tags should all be together with the S-o-b line.

v1 -> v2:
- Used TH_LOG instead of printf for error logging
- Moved variable declaration to the top of the function
- Applied review suggestion by Kees Cook

This patch is against your v1 patch -- it doesn't apply to the seccomp tree as-is. Please rebase your v2 off of the upstream tree rather than your v1.
- rc = get_nth(_metadata, proc_path, 3, &line);
- ASSERT_EQ(rc, 1) {
Indenting looks wrong here, double-check you're using tabs. (And please use scripts/checkpatch.pl to check your patch for common errors.)
TH_LOG("user_notification_fifo: failed to read stat for PID %d (rc=%d)", pid, rc);
- } status = *line; free(line);
Code-wise, it looks good. Please respin for a v3 and this change should be good to land.
