Revision 95c365617aa37878592f2f1c6c64e1abb19f0d4a authored by Wang Nan on 26 February 2016, 09:32:17 UTC, committed by Arnaldo Carvalho de Melo on 03 March 2016, 14:10:36 UTC
perf_evlist__mmap_ex() can fail without setting errno (for example, fail in condition checking. In this case all syscall is success). If this happen, record__open() incorrectly returns 0. Force setting rc is a quick way to avoid this problem, or we have to follow all possible code path in perf_evlist__mmap_ex() to make sure there's at least one system call before returning an error.
