Subject: [PATCH 0/3] lib/bug: concurrency fix, cleanups, and debugfs inspection
Date: Sun, 15 Mar 2026 19:49:36 +0000 [thread overview]
Message-ID: <20260315194939.328612-1-objecting@objecting.org> (raw)
Small series for lib/bug.c:
- Fix a KCSAN data race on bug->flags by using READ_ONCE/WRITE_ONCE
and correcting the misleading comment about concurrency (patch 1).
- Clean up const-correctness and bare 'unsigned' types (patch 2).
- Add /sys/kernel/debug/bug_sites to inspect registered BUG/WARN
sites and their runtime state, complementing the existing
clear_warn_once interface (patch 3).
Build-tested with W=123.
Josh Law (3):
lib/bug: annotate concurrent access to bug->flags with
READ_ONCE/WRITE_ONCE
lib/bug: clean up types in bug reporting helpers
lib/bug: add debugfs interface to list all BUG/WARN sites
