Oleg Nesterov dd71cca58a dump/x86: sanitize the ERESTART_RESTARTBLOCK -> EINTR transition ... 1. The -ERESTART_RESTARTBLOCK case in get_task_regs() depends on kernel internals too much, and for no reason. We shouldn't rely on fact that a) we are going to do sigreturn() and b) restore_sigcontext() always sets restart_block->fn = do_no_restart_syscall which returns -EINTR. Just change this code to enforce -EINTR after restore, this is what we actually want until we teach criu to handle ERESTART_RESTARTBLOCK. 2. Add pr_warn() to make the potential bug-reports more understandable, a sane application should handle -EINTR correctly but this is not always the case.
