Impact: fix redundant and incorrect check Oleg Nesterov noticed wrt commit: 14fc9fb: x86: signal: check signal stack overflow properly >> No need to check SA_ONSTACK if we're already using alternate signal stack. > > Yes, but this also mean that we don't need sas_ss_flags() under > "if (!onsigstack)", Checking on_sig_stack() in sas_ss_flags() at get_sigframe() is redundant and not correct on 64 bit. To check sas_ss_size is enough.
