Series | Fix clang static analysis null pointer bugs. | expand |
This looks fine to me. If you end up needing to re-work this patch series, I think it would be appropriate to combine this with patch #4 since this is essentially fixing the same possible NULL pointer.

Clang reports possible null pointer 'argv[0]' to execvp. Fix it by adding ovs_assert check. Signed-off-by: William Tu <u9012063@gmail.com> --- lib/process.c | 1 + 1 file changed, 1 insertion(+)
