Subject: [PATCH v2 01/10] perf symbol: Reduce scope of elf__needs_adjust_symbols
Date: Mon,  1 Dec 2025 12:55:00 -0800	[thread overview]
Message-ID: <20251201205509.195451-2-irogers@google.com> (raw)
In-Reply-To: <20251201205509.195451-1-irogers@google.com>

Function is only used by symsrc__init in symbol-elf.c, make static to
reduce scope. Switch to not passing the argument by value but as a
pointer.
