Subject: signals: allow the kernel to actually kill /sbin/init
X-Git-Tag: v2.6.26-rc1~274
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=80fe728d593e3a048a56610de932919f7d6d968a;p=pandora-kernel.git

signals: allow the kernel to actually kill /sbin/init

Currently the buggy /sbin/init hangs if SIGSEGV/etc happens.  The kernel sends
the signal, init dequeues it and ignores, returns from the exception, repeats
the faulting instruction, and so on forever.

Imho, such a behaviour is not good.  I think that the explicit loud death of
the buggy /sbin/init is better than the silent hang.

Change force_sig_info() to clear SIGNAL_UNKILLABLE when the task should be
really killed.
