perf annotate: Make sure to call symbol__annotate2() in TUI
The symbol__annotate2() initializes some data structures needed by TUI. It has a logic to prevent calling it multiple times by checking if it has the annotated source. But data type profiling uses a different code (symbol__annotate) to allocate the annotated lines in advance. So TUI missed to call symbol__annotate2() when it shows the annotation browser. Make symbol__annotate() reentrant and handle that situation properly. This fixes a crash in the annotation browser started by perf report in TUI like below. $ perf report -s type,sym --tui # and press 'a' key and then move down Fixes: 81e57deec325 ("perf report: Support data type profiling") Reviewed-by: Ian Rogers <irogers@google.com> Signed-off-by: Namhyung Kim <namhyung@kernel.org> Link: https://lore.kernel.org/r/20240405211800.1412920-2-namhyung@kernel.org
