    signal: Simplify and fix kdb_send_sig · 0b44bf9a
    Eric W. Biederman 提交于
    - Rename from kdb_send_sig_info to kdb_send_sig
      As there is no meaningful siginfo sent
    
    - Use SEND_SIG_PRIV instead of generating a siginfo for a kdb
      signal.  The generated siginfo had a bogus rationale and was
      not correct in the face of pid namespaces.  SEND_SIG_PRIV
      is simpler and actually correct.
    
    - As the code grabs siglock just send the signal with siglock
      held instead of dropping siglock and attempting to grab it again.
    
    - Move the sig_valid test into kdb_kill where it can generate
      a good error message.
