hello... > if pending signals are being checked only when switching back to user > space, why it's allowed to use signals in kernel space (between > kernel objects) .. i've read once that in kernel space you can't use > signals , correct me please Honestly I really don't know the core idea why it's allowed to use signals between kernel objects. IMHO, if the kernel objects is working on behalf of a process, maybe the signal is useful, but if not (e.g working in interrupt context), I don't see any usefulness as signal is always queued to certain task_struct. Check ret_from_syscall in entry.S, this is where I got the above conclusion. But again, you can CMIIW. regards Mulyadi -- Kernelnewbies: Help each other learn about the Linux kernel.
