perf list: Sort the output of 'perf list' to view more clearly
Sort the output according to ASCII character list (using strcmp), which supports both number sequence and alphabet sequence. Example: Before this patch: $ perf list List of pre-defined events (to be used in -e): cpu-cycles OR cycles [Hardware event] instructions [Hardware event] cache-references [Hardware event] cache-misses [Hardware event] branch-instructions OR branches [Hardware event] branch-misses [Hardware event] bus-cycles [Hardware event] ... ... jbd2:jbd2_start_commit [Tracepoint event] jbd2:jbd2_commit_locking [Tracepoint event] jbd2:jbd2_run_stats [Tracepoint event] block:block_rq_issue [Tracepoint event] block:block_bio_complete [Tracepoint event] block:block_bio_backmerge [Tracepoint event] block:block_getrq [Tracepoint event] ... ... After this patch: $ perf list List of pre-defined events (to be used in -e): branch-instructions OR branches [Hardware event] branch-misses [Hardware event] bus-cycles [Hardware event] cache-misses [Hardware event] cache-references [Hardware event] cpu-cycles OR cycles [Hardware event] instructions [Hardware event] ... ... block:block_bio_backmerge [Tracepoint event] block:block_bio_complete [Tracepoint event] block:block_getrq [Tracepoint event] block:block_rq_issue [Tracepoint event] jbd2:jbd2_commit_locking [Tracepoint event] jbd2:jbd2_run_stats [Tracepoint event] jbd2:jbd2_start_commit [Tracepoint event] ... ...
