Hi, When a process dumps core, the do_coredump() initiates the core file generation. Is this operation synchronous(does the kernel wait for core to be completely written to disk) ? Basically, if I have the parent process waiting for exit of child which dumped core, can the parent access the core immediately on receipt of "child exit" message ? Is it possible that the core is still in the process of being written ? If so, what's the event the parent needs to wait for to be assured of a complete core.
