See sigmask_to_save(), this is what the kernel records in uc.uc_sigmask before the signal handler runs, after that current->saved_sigmask has no meaning. When signal handler returns it does sys_rt_sigreturn() which restores the original mask saved in uc_sigmask. > What happens if a signal handler calls something that > would normally write to current->saved_sigmask? See above. Oleg.
