Date: Mon, 20 Sep 2010 15:13:14 +0100 From: David Howells <dhowells@...hat.com> To: torvalds@...l.org, akpm@...ux-foundation.org Cc: linux-kernel@...r.kernel.org, Al Viro <viro@...iv.linux.org.uk>, David Howells <dhowells@...hat.com> Subject: [PATCH 3/5] frv: avoid infinite loop of SIGSEGV delivery From: Al Viro <viro@....linux.org.uk> Use force_sigsegv() rather than force_sig(SIGSEGV, ...) as the former resets the SEGV handler pointer which will kill the process, rather than leaving it open to an infinite loop if the SEGV handler itself caused a SEGV signal.
