| Subject: perf annotate: Propagate perf_env__arch() error |
| |
| From: Arnaldo Carvalho de Melo <acme@redhat.com> |
| |
| [ Upstream commit a66fa0619a0ae3585ef09e9c33ecfb5c7c6cb72b ] |
| |
| The callers of symbol__annotate2() use symbol__strerror_disassemble() to |
| convert its failure returns into a human readable string, so |
| propagate error values from functions it calls, starting with |
| perf_env__arch() that when fails the right thing to do is to look at |
| 'errno' to see why its possible call to uname() failed. |
