perf report: Fix crash showing warning related to kernel maps
While testing https://lkml.org/lkml/2012/4/10/123 I hit this crash:
(gdb) bt
0 0x000000000042000f in __cmd_report (rep=0x7fff80cec580) at builtin-report.c:380
1 cmd_report (argc=0, argv=<optimized out>, prefix=<optimized out>) at builtin-report.c:759
2 0x0000000000414513 in run_builtin (p=0x7724a8, argc=3, argv=0x7fff80ceca70) at perf.c:273
3 0x0000000000413d41 in handle_internal_command (argv=0x7fff80ceca70, argc=3) at perf.c:345
4 run_argv (argv=0x7fff80cec880, argcp=0x7fff80cec88c) at perf.c:389
5 main (argc=3, argv=0x7fff80ceca70) at perf.c:487
kernel_map can be NULL, so need to handle it while dumping a warning
to user.
v2:
- fixed RB_EMPTY_ROOT check -- desc takes the altnerative output when RB_EMPTY_ROOT is false.
