Subject: [PATCH v1 06/10] perf comm: Add __guarded_by annotations to struct comm_strs
Date: Tue, 13 Oct 2026 11:24:54 -0700	[thread overview]
Message-ID: <20261013182458.1234616-7-irogers@google.com> (raw)
In-Reply-To: <20261013182458.1234616-1-irogers@google.com>

Annotate strs, num_strs, and capacity in struct comm_strs with
__guarded_by(&lock) and __pt_guarded_by(&lock) so Clang verifies all
accesses hold comm_strs->lock.

Assisted-by: Antigravity:gemini-3.1-pro
