Message-Id: <1453499078-9330-2-git-send-email-chris.j.arges@canonical.com> Date: Fri, 22 Jan 2016 15:44:37 -0600 From: Chris J Arges <chris.j.arges@...onical.com> To: jpoimboe@...hat.com, live-patching@...r.kernel.org, x86@...nel.org, pbonzini@...hat.com Cc: gleb@...nel.org, tglx@...utronix.de, mingo@...hat.com, hpa@...or.com, kvm@...r.kernel.org, linux-kernel@...r.kernel.org, Chris J Arges <chris.j.arges@...onical.com> Subject: [PATCH 1/2] tools/stacktool: Add __reiserfs_panic to global_noreturns list The following false positives were noticed with stacktool: stacktool: fs/reiserfs/namei.o: set_de_name_and_namelen()+0x9e: return without frame pointer restore stacktool: fs/reiserfs/namei.o: set_de_name_and_namelen()+0x89: duplicate frame pointer save stacktool: fs/reiserfs/namei.o: set_de_name_and_namelen()+0x8a: duplicate frame pointer setup stacktool: fs/reiserfs/namei.o: set_de_name_and_namelen()+0x9e: frame pointer state mismatch stacktool: fs/reiserfs/namei.o: set_de_name_and_namelen()+0x0: frame pointer state mismatch These all call into '__reiserfs_panic' which has a noreturn attribute. Add this to the global list because this particular attribute cannot be determined from reading the ELF object.
